<title><![CDATA[Pump and motor assembly]]></title>
<link>http://www.freepatentsonline.com/7614855.html</link>
<description><![CDATA[A fluid pumping system that includes a motor and a pump, wherein an output shaft of the motor is directly coupled to an input shaft of the pump. This coupling between the output shaft of the motor and the input shaft of the pump may be the primary mechanism for coupling the motor to the pump. Such a configuration may be called a “floating pump mount”, because the pump is primarily coupled to the motor via the shaft connection. As a result of this connection, the output shaft of the motor may be naturally “aligned” with the input shaft of the pump. To help prevent the pump from freely rotating with the output shaft of the motor during operation, a rotational stop mechanism may be provided. The rotational stop mechanism may include at least one resilient member for absorbing or substantially absorbing at least some of any relative movement between the pump and the motor.]]></description>

<title><![CDATA[Reciprocating compressor and refrigerator having the same]]></title>
<link>http://www.freepatentsonline.com/7614251.html</link>
<description><![CDATA[Disclosed are a reciprocating compressor and a refrigerator having the same. The reciprocating compressor comprises a casing, one reciprocating motor mounted at a frame unit provided in the casing for generating a linear-reciprocation driving force, a first compression unit for compressing a refrigerant directly sucked without passing through the inside of the casing by receiving the driving force of the reciprocating motor, and a second compression unit for mixing a refrigerant introduced into the casing and a refrigerant discharged from the first compression unit and then compressing the mixed refrigerant once more by receiving the driving force of the reciprocating motor. Accordingly, a refrigerant is consecutively compressed two times, components are simplified, and the compressor is easily controlled. Also, the refrigerator having the reciprocating compressor decreases a load of the reciprocating compressor thereby to enhance the efficiency of the refrigerator.]]></description>

<title><![CDATA[Multichamber tank for motor vehicles]]></title>
<link>http://www.freepatentsonline.com/7614854.html</link>
<description><![CDATA[A multichamber tank for motor vehicles comprises two chambers ( 4, 5 ) connected via a constricted region ( 6 ) located high up in the chambers, a first chamber ( 4 ) having a filler neck ( 2 ), and a line ( 13 ) bridging the constriction forming the connection to a second chamber ( 5 ). In order that both chambers are filled at approximately the same speed during filling-up through the filler neck ( 2 ), a pump ( 11 ) designed for level equalization during filling-up and driven by an electric motor ( 12 ) is provided in the line ( 13 ), and a level sensor ( 17, 18 ) is provided in each of the two chambers ( 4, 5 ), the output signals of which sensors are available to a control unit ( 14 ) which controls the electric motor ( 12 ) of the pump ( 11 ).]]></description>

<title><![CDATA[Medical pump device]]></title>
<link>http://www.freepatentsonline.com/7614857.html</link>
<description><![CDATA[The invention relates to a medical pump device comprising a rotary valve ( 13 ) having preferably only one rectilinear channel ( 20 ) which respectively connects the inlet ( 4 ) and the outlet ( 7 ) of the pump device, or connects the inlet to a pump chamber ( 15 ), or said pump chamber to the outlet, upon rotation of the rotary element ( 19 ) of the valve. The invention enables a medical pump device to be especially easily produced, said pump device being preferably inserted between an infusion syringe driver or an infusion container and a catheter, and being used to supply small quantities of liquid in an accurately dosed manner.]]></description>

<description><![CDATA[A manually operable priming pump has a housing formed with an inlet port adapted to be connected to a supply of fuel and an outlet port adapted to be connected to a fuel-delivery system, a body in the housing between the ports and formed with a throughgoing main passage that is completely clear of obstructions. The body is shiftable between an operating position in which the main passage is aligned with the inlet and outlet ports and permits free flow therebetween and a pumping position, and a piston in the body can be manually reciprocated in the pumping position to draw fluid in through the inlet port and expel it from the outlet port.]]></description>

<title><![CDATA[Centrifugal fan with air guide]]></title>
<link>http://www.freepatentsonline.com/7614250.html</link>
<description><![CDATA[The present invention obtains a desired cooling effect in a fan motor as well as suppresses any increase in the noise level in a centrifugal fan that sucks in air from the rotary shaft direction and blows out air in a direction that intersects the rotary shaft, and in an air conditioner provided therewith. The centrifugal fan of the air conditioner comprises a fan motor, a hub, a plurality of blades, and an air guide. The hub has cooling air holes, and is coupled to and rotationally driven by a shaft of the fan motor. The air guide guides a portion of the blown out air to the vicinity of the fan motor, cools the fan motor, and then guides the air flow so that the revolving direction velocity decreases when that air is blown out from the cooling air holes to the side of the hub opposite the fan motor.]]></description>

<title><![CDATA[Linear motor, and linear compressor using the same]]></title>
<link>http://www.freepatentsonline.com/7614856.html</link>
<description><![CDATA[A linear motor of the present invention has: a stator having a stationary iron core and a magnet wire; a mover having a moving iron core and a magnet; and a plate-shaped elastic member for supporting the mover in a manner to rock in the rocking directions. This construction eliminates a sliding portion for supporting the mover so that it can reduce the loss, which might otherwise accompany the reciprocation of the mover. Moreover, a linear compressor using this linear motor is high in efficiency and reliability.]]></description>

<title><![CDATA[Charged particle beam apparatus]]></title>
<link>http://www.freepatentsonline.com/7615765.html</link>
<description><![CDATA[There is provided a compact charged particle beam apparatus with a non-evaporable getter pump which maintains high vacuum even during emission of an electron beam without generating foreign particles. The apparatus comprises: a charged particle source; a charged particle optics which focuses a charged particle beam emitted from the charged particle source on a sample and performs scanning; and means of vacuum pumping which evacuates the charged particle optics. The means of vacuum pumping has a differential pumping structure with two or more vacuum chambers connected through an opening in series. A pump made of non-evaporable getter alloy is placed in an upstream vacuum chamber with a high degree of vacuum, and a gas absorbing surface of the non-evaporable getter alloy is fixed without contact with another part.]]></description>

<link>http://www.freepatentsonline.com/7615122.html</link>
<description><![CDATA[A method and apparatus provides for dispensing a liquid concentrate. The source pressure of a liquid diluent is changed by a boost pump ( 52 ) to bring the pressure of the diluent to an elevated pressure. The diluent then enters an aspirator assembly ( 10 ) wherein the concentrate and diluent are mixed to form a use solution. The dynamic pressure of the diluent entering the aspirator assembly ( 10 ) is sufficient so that the amount of concentrate delivered over time is more constant.]]></description>
