| 一种固定容量泵(P)，通过导管(Rp)和吸入通道(1)从容器(R)吸入工作油，并将加压的工作油排出到连接着致动器(A)的排出通道(2)中。节流器(21)布置在排出通道(2)中，而流量控制阀(F)根据节流器(21)产生的压力损失，将节流器(21)上游的排出通道(2)中的部分工作油回流至吸入通道(1)。节流器(21)在低温情况下显著增大流动阻力的这种特性，使得回流工作油的流量增大，因此防止在低温状态下高速工作时在泵(P)中产生空穴/噪音。 | ||||||

| A variable capacity type oil pump, which is driven by an engine, supplies hydraulic pressure to a hydraulic control circuit of an automatic transmission. A range switch mechanism, which includes a motor as a motive power source, switches a shift range of the automatic transmission. Further, a switch operation mechanism, which switches a discharge amount of the oil pump, is driven by the motor of the range switch mechanism. In this case, an operative position of the switch operation mechanism is switched by the motor according to an input rotation speed of the oil pump, thereby switching the discharge amount of the oil pump. Accordingly, the motor of the range switch mechanism is used to drive the switch operation mechanism to switch the discharge amount of the oil pump, and thus a motive power source dedicated to changing the discharge amount of the oil pump is not needed. | ||||||

| A fixed capacity pump (P) sucks working oil from a reservoir (R) through a conduit (Rp) and a suction passage (1), and discharges the pressurized working oil into a discharge passage (2) connected to an actuator (A). A choke (21) is disposed in the discharge passage (2), and a flow control valve (F) recirculates a part of the working oil in the discharge passage (2) upstream of the choke (21) to the suction passage (1) according to a pressure loss generated by the choke (21). The characteristic of the choke (21) which significantly increases the flow resistance in a low temperature state makes the flow rate of the recirculated working oil increase, thereby preventing cavitation/noise from occurring in the pump (P) when operated at high speed and in a low temperature state. | ||||||

| 【課題】可変容量型のオイルポンプを備えた油圧供給システムを低コスト化・省スペース化できるようにする。 【解決手段】エンジン11で駆動される可変容量型のオイルポンプ34で自動変速機12の油圧制御回路13に油圧を供給し、モータ27を駆動源とするレンジ切換機構16で自動変速機12のシフトレンジを切り換える。更に、オイルポンプ34の吐出量を変更するための切換動作を行う切換動作機構をレンジ切換機構16のモータ27で駆動する。その際、オイルポンプ34の入力回転速度に応じてモータ27で切換動作機構の動作位置を切り換えてオイルポンプ34の吐出量を切り換える。これにより、レンジ切換機構16のモータ27を利用して切換動作機構を駆動してオイルポンプ34の吐出量を変更することができ、オイルポンプ34の吐出量を変更するための専用の駆動源を設ける必要がなくなる。 【選択図】図1 |
