摘要： An oil pump rotor includes an inner rotor formed with n (n: a natural number) external teeth, and an outer rotor formed with n+1 internal teeth which are in meshing engagement with each of the external teeth. And the oil pump rotor is used in an oil pump that includes a casing having a suction port for drawing in fluid and a discharge port for discharging fluid and conveys the fluid by drawing in and discharging the fluid due to changes in volumes of cells formed between surfaces of the internal teeth and surfaces of the external teeth during rotations of the rotors under meshing engagement therebetween. And the tooth profile of the external teeth of the inner rotor is formed by a deformation in the circumferential direction and a deformation in the radial direction applied to a profile defined by a mathematical curve with the deformation in the circumferential direction is applied while maintaining the distance between the radius (RA1) of an addendum circle (A1) and the radius (RA2) of the tooth groove circle (A2).

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.
