Abstract: A gas vane pump wherein a lubricant is intermittently introduced into a housing during rotation of a rotor, through a supply passage formed through the housing and the rotor, and the relative position between the rotor having a diametric hole and the housing having a communication groove is determined such that when the rotor is at an angular position in the middle of a predetermined angular range relative to the housing and the hole is in communication with the groove, a point of contact between a vane movably held by the rotor and the inner circumferential surface of the housing is located at the lowest position of the inner circumferential surface. When the rotor is stopped within the predetermined angular range, the vane divides the remaining lubricant into two portions, which are discharged at different times, making it possible to reduce the load on the vane upon restarting the pump.

Abstract: A radial piston pump includes cylinders oriented radially to an axis of rotation of an eccentric shaft and pistons arranged radially movably in the cylinders against the force of a spring member such that the pistons are pressed radially outwards by the rotational movement of an eccentric and radially inwards by the spring members. The pistons have at least one inlet opening connected to an inlet chamber of a pumping medium in the radially inner position of the pistons, and the pumping medium is pressed into a pressure area during the radially outward movement of the pistons. An eccentric shaft is mounted in sliding bearings arranged on both sides of the eccentric and the shaft is traction driven. A pressure connection between an annular duct and one of the sliding bearings advantageously provides a bearing gap between the sliding bearing and the eccentric shaft to constantly supply a close film of oil which has a damping effect upon the radial movements of the eccentric shaft.
