摘要： An oil pump includes a capacity adjustment mechanism that changes the pump capacity by moving a tubular body in a tube radial direction, with a pump chamber formed between the tubular body and an outer circumference side of a rotor, a first spring biasing the tubular body in a direction in which pump capacity increases, a control valve that converts oil pressure of the oil pump into control pressure and causes the control pressure to act on the capacity adjustment mechanism, and a second spring biasing a valve body in order to set the control pressure in the control valve. The relationship of the biasing forces of the first and second springs is set so that pump capacity is set to maximum when the engine rotational speed is less than a predetermined value, and so that pump capacity is reduced when the engine rotational speed exceeds a predetermined value.

摘要： An automatic hydraulic tensioner according to the present invention is provided with a communication mechanism for allowing a space radially inside a plunger-side end wire portion of a coil spring to communicate with a small clearance between the plunger and a cylinder. This automatic hydraulic tensioner thus succeeds, with a simple structure, in preventing bubbles from remaining within a pressure chamber and appropriately maintaining the tension applied to a power transmitting means such as a belt, a chain or the like.
