摘要： A roots pump including a pair of multi-lobe rotors is disclosed. The pair of rotors each include a first straight portion and a second straight portion. The first straight portion is provided on one of end portions of the rotary shaft of the rotor in an axial direction to extend straight along the axial direction. The straight portion is provided on the other one of the end portions to extend straight along the axial direction. The phases of the first straight portion and the second straight portion are displaced along the circumferential direction of the associated rotary shaft. Each of the pair of rotors further includes a coupling portion, which couples the first straight portion and the second straight portion. The coupling portions of the pair of rotors are engaged with each other to suppress fluid leakage between the pair of rotors.

摘要： An air conditioning system 100 may include a compressor 101 having a driving chamber 110, a cooling circuit 151, a heating circuit 152 and a controller 189. This system may release high pressure refrigerant from the compressor discharge port 120 into the compressor driving chamber 110 by means of the controller 189. The controller 189 may include a selector 181, a first refrigerant releasing means 183 and a second refrigerant releasing means 185. The selector 181 connects the discharge port 120 and the driving chamber 110 by both the first and second refrigerant releasing means 183, 185 when discharge pressure of the refrigerant has reached a predetermined high-pressure state during operation of the heating circuit 152. When the discharge pressure of the refrigerant results an abnormal high pressure state during the operation of the heating circuit 152, the high pressure refrigerant is released from the discharge port 120 into the driving chamber 110 not only by a single refrigerant releasing means 185 but by double refrigerant releasing means 183, 185. Therefore, the high pressure refrigerant can be swiftly released into the driving chamber 110 to increase the pressure in the driving chamber 110 and the necessary time for reducing the compressor discharge pressure can be minimized. Thus, the abnormal high discharge pressure can be quickly alleviated.

摘要： A variable displacement compressor in a refrigeration circuit using carbon dioxide refrigerant. The compressor changes the inclination of a swash plate located in a control chamber in accordance with the difference between the pressure in the control chamber and the pressure in a suction chamber thereby varying the compressor displacement. The compressor includes a control valve that adjusts the difference between the pressure in the control chamber and the pressure in the suction pressure. The control valve controls the flow rate of refrigerant supplied from the discharge chamber to the control chamber thereby adjusting the pressure difference. A controller inputs information from the outside of the refrigeration circuit. The outside information includes the outside temperature, the temperature of a passenger compartment and a target compartment temperature set by a temperature adjuster. The controller sets a target value of the pressure of refrigerant discharged from the compressor in accordance with the outside information. The controller then controls the current supplied to the control valve such that the target discharge pressure is rapidly reached. The compressor reduces unnecessary operation thereby reducing the power consumption and the load.

摘要： An electric pump for supplying a hydrogen gas to a fuel cell includes a rotary shaft rotatably inserted through an electric motor, a transmitting member provided on one of an outer peripheral surface of the rotary shaft and an inner peripheral surface of the electric motor so as to be rotatable therewith, and a groove formed in the other of the outer peripheral surface of the rotary shaft and the inner peripheral surface of the electric motor for the transmitting member to be inserted therein. The groove transmits a rotary torque of the electric motor to the rotary shaft by contacting an inner surface of the groove and the transmitting member and has an opening width along a rotary direction of the rotary shaft which is larger than the width of the transmitting member. The groove and the transmitting member produce an impact torque when the electric pump is started.

摘要： In a reciprocating compressor, an adequate lubricating effect is ensured for a sliding surface between a piston and a cylinder bore, and the leakage of a refrigerant for discharge is prevented. After a lubricating oil mixed within the refrigerant is separated by an oil separator 23 on a discharge side, the separated lubricating oil is guided via an oil supply hole 29 in a cylinder block 1 to the sliding surface between the cylinder bore 12 and the piston 13 that reciprocates within the cylinder bore 12 thereof in order to lubricate the surface. In this reciprocating compressor, the intermediate axial portion of the outer circumference of the piston 13 has a small diameter in order to define an oil sump 30. The oil sump 30 is configured so as not to directly communicate with a drive chamber 7, and oil always collects within the oil sump 30.

摘要： A rotary shaft is rotatable relative to a motor rotor. A first end face of the motor rotor is exposed to the outside of a stator. A hammer portion is provided at the first end face. The hammer portion is configured to be movable as the motor rotor rotates. A collision portion rotating integrally with the rotary shaft is configured to collide with the hammer portion. The allowance space between the collision portion and the hammer portion allows the hammer portion to be move relative to the collision portion. Therefore, the electric pump is capable of detaching a rotor from a pump chamber without increasing the size of the pump.

摘要： An air conditioning system includes an compressor 110 having a driving chamber 110, a suction port 116 and a discharge port 121, a first passage 107 that connects the discharge port 121 to the driving chamber 110 by opening a capacity control valve 140, a second passage 105 that connects the driving chamber 110 to the suction port 116 and a driving means 130 that can change the output discharge capacity of the compressor by changing the pressure in the driving chamber 110. The refrigerant can be released from the driving chamber 110 to the suction port 116 separately from the second passage 105 if the driving chamber reaches a predetermined high-pressure state. In such an air conditioning system, abnormally high pressure problems are overcome that utilizes a hot gas bypass heater. In particular, heating performance is improved, because high pressure refrigerant is not released from the hot gas bypass heater circuit into the cooling circuit. Further, an excessively high-pressure state in the driving chamber 110 can be prevented.
