20080247883 | Displacement control valve for variable displacement compressor - A displacement control valve for a variable displacement compressor has a control passage, a valve hole formed in the control passage, a first shaft portion including a valve body, and a connecting portion connected to the end portion of the valve body. The control passage is connected to a crank chamber for controlling the pressure in the crank chamber for adjusting the discharge displacement of the compressor. The valve body is formed at an end portion of the first shaft portion to open and close the valve hole. The connecting portion connected to the end portion of the valve body is disposed into the valve hole, and a circumferential surface of the connecting portion has a curved surface so as to be flared out at an end of the connecting portion. | 10-09-2008 |
20090241766 | VARIABLE DISPLACEMENT COMPRESSOR - A variable displacement compressor includes a housing, a rotary shaft, a bearing, a seal member, a shaft seal chamber, a discharge refrigerant passage and a partition. The partition is provided in the shaft seal chamber for partitioning the shaft seal chamber into a first seal chamber to which the discharge refrigerant passage is opened and a second seal chamber part of the periphery of which is formed by the bearing and the seal member. The partition is provided with a first guide passage through which refrigerant containing lubricating oil flowed from the discharge refrigerant passage into tho first seal chamber is substantially all supplied to the seal member of the second seal chamber. | 10-01-2009 |
20120234021 | HEAT EXCHANGER - A heat exchanger comprises a housing, a guide member, a return member and a discharge member. The housing includes a plurality of parallel flow passages. The housing includes a first end face and a second end face each having openings. The guide member, the return member and the discharge member are fixed to the first end face or the second end face. The plurality of flow passages are connected by the return member into a single flow passage. The guide member and the discharge member are provided in the opening on a most upstream side and a most downstream of the single flow passage, respectively. At least one of the guide member, the return member and the discharge member integrally includes an attachment portion attached to the housing; and a protruding portion protruding more than the attachment portion toward the housing and including an inclined surface. | 09-20-2012 |
20120240596 | THERMOELECTRIC CONVERSION UNIT - A thermoelectric conversion unit includes first and second cases including first and second recesses that define first and second flow passages and have openings, first and second substrates, a plurality of thermoelectric devices in contact with the inner surfaces of the first and second substrates, a connector for joining the first and second cases, first and second fins protruding from the first and second substrates in the first and second flow passages. The first and second cases include first and second opposed portions opposed to the first and second substrates outside the first and second recess, respectively. A spacer for setting distance between the first opposed portion and the second opposed portion is provided. The spacer sets the distance between the first and second opposed portions to be longer than distance between the outer surface of the first substrate and the outer surface of the second substrate. | 09-27-2012 |
20120240598 | HEAT PUMP SYSTEM - One aspect of the present invention may include a heat pump system having a Peltier unit in an outdoor space and an outdoor heat exchange unit in the outdoor space. The Peltier unit has a Peltier element with a heat-absorbing portion and a heat-radiating portion, a first substrate in contact with the heat-absorbing portion, a second substrate in contact with the heat-radiating portion, a metal case and a resin case. The metal case covers the first substrate and forms a first flow path between itself and the first substrate. The first flow path is connected in a loop-like fashion to the outdoor heat exchange unit by an outdoor piping. The resin case covers the second substrate and forms a second flow path between itself and the second substrate. The second flow path is connected in a loop-like fashion to the indoor heat exchange unit by an indoor piping. | 09-27-2012 |
20120247526 | THERMOELECTRIC CONVERSION UNIT AND METHOD OF MANUFACTURING - One aspect of the present invention includes a thermoelectric conversion unit having a case in which a flow path of an open structure is molded, a first substrate covering an open portion of the flow path, a second substrate arranged opposite the first substrate, and a plurality of thermoelectric conversion elements arranged between the first substrate and the second substrate. At a bottom surface of the flow path of the case, an introduction pipe and a discharge pipe are formed integrally with the case, and each of the introduction and discharge pipes extend in a direction perpendicular to the first substrate. | 10-04-2012 |
20150037633 | BATTERY PACK - A battery pack includes a case and a battery module including secondary cells. Each secondary cell includes a primary surface and a secondary surface. The primary surface includes a terminal, and an inter-cell flow passage is formed between adjacent ones of the secondary cells. A primary flow passage is defined between the primary surfaces and a wall surface of the case that faces the primary surfaces. A secondary flow passage is defined between the secondary surfaces and the wall surface of the case that faces the secondary surfaces. One of the primary flow passage and the secondary flow passage functions as a supply passage that supplies a heat medium to the inter-cell flow passage. The other one of the primary flow passage and the secondary flow passage functions as a discharge passage to which the heat medium is discharged from the inter-cell flow passage. | 02-05-2015 |
20150203339 | INDUSTRIAL VEHICLE - An industrial vehicle is provided with a vehicle body, battery cells, which are the electric power source for the industrial vehicle and are located within the vehicle body, and a counterweight, which is located within the vehicle body. The counterweight has a weight portion and a weight body that extends from the weight portion. The battery cells are provided on both sides of the weight body and are thermally coupled to the weight body. | 07-23-2015 |
