Abstract

PURPOSE: To reduce frictional force on a sliding part and prevent seizing on operating at a high speed by providing a cam ring consisting of an inner ring, an outer ring, and steel balls which are provided between the both rings, between the inner face of a housing and a spherical outer end of a plunger.
CONSTITUTION: A cam ring 24 consisting of an inner ring 28, an outer ring 26, and steel balls 30 provided between the both rings, is provided between the inner surface of a housing 10 and the outer end face of a plunger 22. The outer end of the plunger 22 is merely formed into a spherical shape, without a roller or any other member being provided on it, and the plunger 22 is provided in a cylinder bore 20, with an inclination angle of α1, α2 for each plunger. Thereby, when a rotor 18 rotates, the plunger 22 having the inclination angle reciprocates in the cylinder bore 20, while rotating on its axis. Therefore, the inner face of the inner ring 28 is brought in rolling contact with the outer end of the plunger 22, reducing the sliding friction between the both. Accordingly, smooth rotation of a rotor 18 can be obtained, while seizing of a sliding surface can be prevented with a simple construction.
