摘要： PURPOSE: To improve work efficiency, to be favorable in reduction of size, and to improve mounting ability when an oil pump device is mounted on a car body. CONSTITUTION: When the number of revolutions of a rotor 2 is low and an oil pressure through a main delivery port 31 is low, the confluent port 74 of a control valve 7 is released. Oil in a first oil passage 61 through a main delivery port 31 and oil in a second oil passage 62 through a subdelivery port 32 are joined together at a confluent area 5T to ensure a necessary oil pressure. Meanwhile, when the number of revolutions of the rotor 2 and an oil pressure through the main delivery port 31 is increased, the valve body 77 of a control valve 7 is moved in a direction B2, the confluent port 74 is closed to block confluence. A second port 72 is communicated with a feedback port 73, and feedback of working oil in the second oil passage 62 through the feedback port 73 to a feedback oil passage 66 is carried out.

摘要： A method of operating a rolling piston compressor includes determining a pressure difference (ΔP) between a discharge pressure (Pd) within a compression volume and a suction pressure (Ps) within a suction volume; determining a pressure ratio (rp) equal to the discharge pressure (Pd) over the suction pressure (Ps); estimating a discharge pressure (Pd) based at least in part on the pressure difference (ΔP) and the pressure ratio (rp); determining that the discharge pressure (Pd) is greater than a predetermined pressure limit (Pd-limit); and lowering a target speed (ωtarget) of the rolling piston compressor.

摘要： In a hydraulic control device, when it is detected that a pressure of first oil (output pressure) detected by an output pressure sensor pulsates, a transmission control unit as a TCU stops driving of a second pump or decreases a rotation number of the second pump as a first operation. Alternatively, when it is detected that the output pressure pulsates, the TCU increases the rotation number of the second pump to a rotation number (for example, maximum rotation number) that is higher than a target rotation number as a second operation.

摘要： A positive displacement pump for pumping oil in a motor vehicle transmission comprises a pump stage that has a central kidney-shaped suction cavity and two kidney-shaped pressure cavities. Oil is selectively pumped via one kidney-shaped pressure cavity or the other kidney-shaped pressure cavity in accordance with the direction of rotation of the pump stage. This makes it possible to create, with little complexity, two operating stages for the positive displacement pump.

摘要： The invention relates to a valve train of an internal combustion engine having hydraulic actuator means for controlling a valve control means as a function of engine speed and having a pump driven by the engine for supplying the actuator means with working fluid. The pump is configured as a suction-controlled ring-gear pump having a sealing web extending over a plurality of pockets, and featuring a delivery characteristic as a function of speed which is adapted to the working fluid requirement of said actuator means. In addition, an internal gear pump is provided, particularly useful for such a valve train.

摘要： An oil pump system includes an oil pump, a first hydraulic passage, a second hydraulic passage, a return hydraulic passage, and a control valve. When a revolving speed of a rotor of the oil pump is low, and when a hydraulic pressure of a hydraulic oil, discharged out of a first outlet port of the oil pump to the first hydraulic passage, is lower than a predetermined value, a valve body of the control valve is placed at a first position, thereby joining the hydraulic oil, flowing in the first hydraulic passage, with the hydraulic oil, discharged out of a second outlet port of the oil pump to the second hydraulic passage, and delivering the thus joined hydraulic oil to a hydraulic oil receiving unit via a hydraulic-oil-delivery passage. When the revolving speed of the rotor is high, and when the hydraulic pressure of the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, is higher than the predetermined value, the valve body is placed at a second position, thereby inhibiting the hydraulic oil from joining, and delivering only the hydraulic oil, discharged out of the first outlet port to the first hydraulic passage, to the aforementioned destination. The oil pump system is downsized and lightweighted advantageously, and is improved in terms of work efficiency and on-boardability.
摘要翻译：油泵系统包括油泵，第一液压通道，第二液压通道，返回液压通道和控制阀。当油泵的转子的旋转速度低时，当从油泵的第一出口向第一液压通路排出的液压油的液压低于预定值时，阀将控制阀的主体放置在第一位置，从而将在第一液压通路中流动的液压油与液压油接合，从油泵的第二出口排出到第二液压通路，从而通过液压油输送通道将液压油接合到液压油接收单元。当转子的旋转速度高时，并且当从第一出口到第一液压通路排出的液压油的液压高于预定值时，阀体被置于第二位置，从而阻止液压油接合，并且仅将从第一出口排出的液压油输送到第一液压通道到达上述目的地。油泵系统有利地小型化和轻量化，并且在工作效率和车载性方面得到改进。
