| PURPOSE: To dispose a pressure control valve which has its switching pressure set at a given pressure, allows the extension/contraction stroke of a spring controlling the displacement operation of each spool valve to be made short without a hitch, and can enhance the degree of freedom for the selection of location. CONSTITUTION: The variable capacity oil pump is equipped with an oil port 2 which can simultaneously discharge oils different in pressure and discharge, and with a pressure control valve 1 which can relieve a part of its discharge in response to its discharging pressure, provides the pressure adjusting valve 1 with a plurality of spool valves 22 and 23, and with a plurality of springs 24 and 25 controlling each spool valve to be different discharging pressure, and allows the capacity of oil to be fed to an engine to be made variable through the pressure control valve 1.

| PURPOSE: To prevent hydraulic pressure and abnormal rise of the hydraulic pressure by providing a main pump and a sub pump the rotor axes of which make contact with and part from each other in accordance with the magnitude of a discharge pressure, side by side, in a casing and cutting off the sub rotor axis from the main rotor axis when they rotate at a high speed and the discharge pressure becomes high. CONSTITUTION: A main rotor axis 8 fastened on the main inner rotor 4 of a main pump and a sub rotor axis 9 fitted free to slide, on the sub inner rotor 6 of a sub pump are connected to each other by the engagement of a sliding rod 10 with a slid hole of elliptical sections, etc., on their facing edge sides. And the sub rotor axis 9 flips outward against the main rotor axis 10 with a flipping body 12 and usually makes an engaging part 14, which is set protrusively on the sub rotor axis 9, engage with an engaged part 7 formed on the sub inner rotor 6. And when the main pump comes in a high speed driven state and the pressure in a discharge pressure detection passage 18 becomes high, the sub rotor 9 is made to move to the right against the flipping body 12 with the pressure, the engagement of the engaged part 7 with the engaging part 14 is released to stop the sub pump and the discharge pressure is reduced.

| PURPOSE: To make a pump as a whole lighter and smaller by removing a side plate and a pressure plate. CONSTITUTION: A pair of spool valves 40, 41 which function as flow control valves and selector valves are jointly installed in a direction nearly perpendicularly intersecting to the rotary shaft 20 of a rotor 12 in a front body 15 or in a rear body 16, while a pump suction-side passage and the first and second pump delivery side passages 36, 37 are constructed from each pump chamber 30 in a pump cartridge 14 to said each spool valve 40, 41, in such a way that the passages formed by means of inner rings or machining in each body 15, 16 are appropriately connected. Thereby each part can be molded and assembled easily while making the pump as a whole smaller, lighter and less costly. COPYRIGHT: (C)1984,JPO&Japio | ||||||

| 主オイル供給路9内の圧力が無負荷運転開始圧よりも小さいときには、副オイル供給路10内の圧油はスプール20の内部流路21を通過して主オイル供給路9内に流入する。このとき主副両オイルポンプ7,8からの吐出油は合流した状態でオイル供給対象OBへ送られる。主オイル供給路9内の圧力が上昇して上記無負荷運転開始圧に達したときには、スプール20はスプリング30による付勢方向とは反対の方向に移動して副オイル供給路10内の圧油をドレンし、ポペット40はスプール20と接触してスプール20の内部流路21を閉止する。このとき副オイルポンプ8は無負荷運転状態となり、主オイルポンプ7の吐出油のみがオイル供給対象OBに送られる。 | ||||||

| PROBLEM TO BE SOLVED: To provide a motor control device and an electric pump unit which are able to minimize heat generation and noise by suppressing over power, and which can accommodate even load change.SOLUTION: A control circuit 21 includes an over power suppression control means 32 for suppressing over power by reducing a current command value from a higher-level ECU 19. A control signal output means 31 adds a reduction amount for a current command value obtained by the over power suppression control means 32 to a current command value from the higher-level ECU 19 to thus obtain a motor control signal. The over power suppression control means 32 includes a hydraulic pressure estimation part 34 for estimating hydraulic pressure and a current command value correction amount computation part 35 for comparing target hydraulic pressure with estimated hydraulic pressure to output a reduction amount for the current command value. Load information about relative magnitude relation of loads of a pump 3 is configured to be input to the control circuit 21 from the higher-level ECU 19. In the over power suppression control means 32, the target hydraulic pressure is configured to be switched correspondingly to different load information. | ||||||
