摘要： A pump is provided, which includes: an internal housing inside which a vane rotor is housed; a pump housing 1 in which the centre of rotation of the vane rotor is immovable and the internal housing is able to move; a first control oil chamber which causes the internal housing to move in a direction of decreasing the discharge volume; and a second control oil chamber which causes the internal housing to move in a direction of increasing the discharge volume; a pressure adjustment valve; a temperature-sensitive valve; and an elastic member which elastically impels the internal housing. A flow passage area of the temperature-sensitive valve changes gradually with change in oil temperature, and the pressure adjustment valve changes a discharge volume in accordance with increase in pressure of the discharge oil.

摘要： A drive power distribution device includes a hydraulic pressure sealing-type hydraulic pressure control device for making an operation noise of an on-off valve such as a solenoid valve less recognizable to occupants of a vehicle. By closing the on-off valve and driving the oil pump, a hydraulic pressure detected using a hydraulic pressure detection means reaches a target hydraulic pressure, and fastening power of a hydraulic clutch is maintained at an oil pressure of hydraulic fluid sealed in an oil passage until the on-off valve is opened. The drive power distribution device closes the solenoid valve when the hydraulic pressure is detected to be equal to or less than a predetermined threshold hydraulic pressure and equal to or less than a predetermined threshold vehicle speed. This can prevent synchronization between an accelerator operation by a driver and a closing operation of the solenoid valve.
摘要翻译：驱动配电装置包括液压密封型液压控制装置，用于使诸如电磁阀的开关阀的操作噪声对车辆的乘客不太可识别。通过关闭开关阀并驱动油泵，使用液压检测装置检测到的液压达到目标液压，并且液压离合器的紧固力保持在密封在油路中的液压流体的油压直到开关阀打开。当检测到液压压力等于或小于预定阈值液压并且等于或小于预定阈值车辆速度时，驱动配电装置关闭电磁阀。这可以防止驾驶员的加速器操作与电磁阀的关闭操作之间的同步。

摘要： A high-performance oil pump for pumping oil in an internal combustion engine that eliminates or greatly reduces cavitation in the oil pump, thereby increasing the efficiency and performance of the oil pump. The present invention provides a housing having an inlet for receiving a supply of oil and an outlet for discharging the oil. At least two gears rotatably and matingly are disposed within the housing for pumping the oil from the inlet to the outlet. A pressure regulation circuit is disposed within the housing for balancing oil flow pressure between the inlet and the outlet by redirecting a portion of the oil from the outlet to the inlet when said oil flow pressure reaches a predetermined level at the outlet in order to reduce or eliminate cavitation of oil in the oil pump.

摘要： Delivery units are already known, having a drive rotor and an output rotor driven by the drive rotor, which are rotatably mounted in a rotor housing and interact in a meshing manner via spur toothing in each case, at least one of the two rotors being axially adjustable and, on the rear side thereof, facing away from the other rotor, having a compensating pressure applied via a compensation channel. The compensating pressure acts firstly counter to the axial compressive forces which arise in the working chambers formed between the rotors, and secondly compensates for the forces which would force the two rotors apart. This ensures that the distance between the rotors does not change. The compensating pressure frequently corresponds to the pressure on the pressure side of the delivery unit, which means that the forces on the rotors are considerably higher than necessary. This leads to increased friction in the bearings and between the rotors. The rear side of the rotors can also be supplied via slot flows. This has the disadvantage that an undefined compensating pressure is established, which depends on the leakage flows which flow into the space or out of the space behind the rotor. In addition, in this embodiment the compensating pressure does not have the ideal value for low-friction operation. In the delivery unit according to the invention, a defined compensating pressure is established on the rear side of the axially adjustable rotors. The invention provides for a control valve (14) to be provided, which sets the compensating pressure to a predetermined value between a pressure on the pressure side and a pressure on the suction side.
摘要翻译：输送单元是已知的，其具有驱动转子和由驱动转子驱动的输出转子，其可旋转地安装在转子壳体中并且以啮合方式通过每个壳体中的正齿相互作用，两个转子中的至少一个轴向并且在其后侧上面向远离另一个转子，具有通过补偿通道施加的补偿压力。补偿压力首先与在转子之间形成的工作室中产生的轴向压力作用相反，其次补偿将两个转子分开的力。这确保转子之间的距离不变。补偿压力经常对应于输送单元的压力侧的压力，这意味着转子上的力明显高于必要。这导致轴承和转子之间的摩擦增加。转子的后侧也可以通过槽流供给。这具有不确定的补偿压力的缺点，这取决于流入空间或离开转子后面的空间的泄漏流。此外，在本实施例中，补偿压力不具有低摩擦操作的理想值。在根据本发明的输送单元中，在可轴向调节的转子的后侧上建立了限定的补偿压力。本发明提供一种要设置的控制阀（14），其将补偿压力设定在压力侧的压力和吸入侧的压力之间的预定值。
