    • The variable displacement gear pump for a loading system in an industrial vehicle has main and sub gear pump portions, suction, discharge and bypass passages, and check and opening valves. The main gear pump portion has main drive and driven gears, and has suction and discharge side spaces. The sub gear pump portion has sub drive and driven gears, and has suction and discharge side spaces. The bypass passage returns hydraulic fluid in the discharge-side space of the sub gear pump portion to the suction passage. The check valve prevents hydraulic fluid in the discharge-side space of the main gear pump portion from flowing to that of the sub gear pump portion. The opening valve is used for opening and closing the bypass passage, and closes the bypass passage due to a pressure in a discharge conduit of the loading system increased by the load applied to the loading system.
    • 用于工业车辆中的装载系统的可变排量齿轮泵具有主副齿轮泵部分,抽吸,排放和旁通通道以及检查和打开阀。 主齿轮泵部分具有主驱动齿轮和从动齿轮,并且具有抽吸和排出侧空间。 副齿轮泵部分具有副驱动齿轮和从动齿轮,并且具有吸入和排出侧空间。 旁路通路将副齿轮泵部的排出侧空间的液压流体返回到吸入通路。 止回阀防止主齿轮泵部分的排出侧空间中的液压流体流向副齿轮泵部分的液压流体。 打开阀用于打开和关闭旁路通道,并且由于加载系统的排放管道中的压力增加到施加到装载系统的负载而使旁通通道关闭。

    • The present invention relates to a refrigerating system and a method of operating a refrigerating system. The refrigerating system includes a compressor, a gas cooler used as a heat-dissipation type heat exchanger, an expansion valve used as a throttling means, an evaporator used as a heat-absorption type heat exchanger and an accumulator, which are connected in series with each other to form a closed circuit. The closed circuit is adapted so that the higher pressure of the closed circuit becomes the supercritical pressure of a refrigerant circulating the closed circuit. This has a control characteristic property wherein the lower evaporating pressure increases as the higher pressure increases. The lower evaporating pressure and the higher pressure are detected, respectively, and if the detected value of the lower evaporating pressure is lower than a target value for the lower evaporating pressure determined based on the above control characteristic property in correspondence to the detected value of the higher pressure, the discharge capacity of the compressor is reduced so that the lower evaporating pressure coincides with the target value.

    • A piston type compressor has a plurality of cylinder bores in which a plurality of pistons reciprocate to effect suction, compression and discharge of refrigerant gas in response to rotation of a drive shaft. The compressor has a gas receiving chamber for receiving the refrigerant gas before compression, a discharge chamber for receiving the compressed gas, and at least one rotary valve mounted on the drive shaft to be rotatable with the drive shaft. The rotary valve has a suction passageway for providing fluid communication between the gas receiving chamber and each of the compression chambers formed in the cylinder bores. A groove is provided on the outer circumferential wall of the rotary valve. The groove is connected with the outlet of the suction passageway and extends to a vicinity of the opposing end portions along the outer circumferential wall. The groove supplies the lubricant oil within the refrigerant gas in the suction passageway to and between the outer circumferential wall of the rotary valve and the inner wall of the recessed chamber during the rotation of the rotary valve.

    • A variable displacement rotary pump includes a main pump unit, an auxiliary pump unit, a discharge passage, a bypass passage, a suction passage, a check valve and a control valve. The suction passage is in communication with the discharge passage through the bypass passage and a second discharge port. The check valve is disposed in the discharge passage for preventing fluid in a first discharge port of the main pump unit from flowing into the bypass passage. The control valve is operable for opening and closing the bypass passage. When the control valve opens the bypass passage and the check valve closes the discharge passage, flow rate of the fluid discharged from the discharge passage is reduced. A throttle passage is provided in the bypass passage or the control valve for regulating flow of the fluid in early phase of operation of the control valve to open the bypass passage.
    • 可变排量旋转泵包括主泵单元,辅助泵单元,排出通道,旁通通道,吸入通道,止回阀和控制阀。 吸入通路与通过旁路通路的排出通路和第二排出口连通。 止回阀设置在排出通道中,用于防止主泵单元的第一排出口中的流体流入旁通通道。 控制阀可操作以打开和关闭旁路通道。 当控制阀打开旁通通道并且止回阀关闭排出通道时,从排出通道排出的流体的流量减小。 在旁通通道或控制阀中设置有节流通道,用于调节控制阀的早期操作中的流体的流动以打开旁路通道。

    • A roots compressor has a housing, a rotary shaft, a rotor and a layer. The housing defines a pump chamber, a suction port and a discharge port. The suction port and the discharge port adjoin to the pump chamber. The rotary shaft is rotatably supported by the housing. The rotor is connected to the rotary shaft and contained in the pump chamber. Fluid introduced into the pump chamber through the suction port is discharged to the outside of the pump chamber through the discharge port by rotation of the rotor which is driven through the rotary shaft. The layer is formed on an inner peripheral surface of the housing, which defines the pump chamber. The layer is thinner from a side adjacent to the suction port toward a side adjacent to the discharge port in circumferential direction of the housing.
