Oil pump control valve

摘要

An oil pump apparatus which includes an oil pump for being driven by a driving source and for being connected to a plurality of components to which an oil is supplied from the oil pump and a control valve preventing the oil which is unnecessary to the components from flowing into the components, wherein at least one of the components is an actuator operated by an oil pressure generated by the oil pump and wherein the control valve permits the oil of which the quantity is smaller than that of the oil which is consumed by the actuator to flow into the components when the actuator is not operated and the control valve permits the oil of which the quantity is larger than that of the oil which is consumed by the actuator to flow into the components when the actuator is operated. <IMAGE>
