摘要： A variable displacement pump including a chamber volume varying mechanism including a moveable member, a first biasing member always biasing the moveable member in such a direction as to increase volumes of the working fluid chambers, and a second biasing member that is disposed with a set load and applies a biasing force to the moveable member in such a direction as to increase the volumes of the working fluid chambers when the moveable member is displaced against a biasing force of the first biasing member by a predetermined amount or more. The biasing force of the first biasing member is set such that before the moveable member is displaced against the biasing force of the first biasing member, the valve timing control device is shifted to a release state in which an open-and-closure timing of an engine valve is variably controlled.

摘要： A variable displacement oil pump for an automotive engine. The oil pump includes a cam ring accommodating thereinside a pump element having a rotor. The cam ring is swingingly movably accommodated in a housing and biased in a direction to increase an eccentricity amount of the cam ring relative to the axis of the rotor by a biasing member. First and second pressure chambers are defined inside the housing by the outer peripheral section of the cam ring. The first pressure chamber is supplied with a discharge pressure to be applied to the cam ring to oppose to a biasing force of the biasing member. The second pressure chamber is supplied with the discharge pressure to be applied to the cam ring to assist the biasing force of the biasing member. Additionally, a control device is provided for controlling supply of the discharge pressure to the second pressure chamber.
