Abstract

PURPOSE: To prevent counterflow of a pump oil when stopping a pump quickly by a constitution wherein a piston is actuated by an action of a pivot block eccentric and coupled direct to a rotor shaft, and a lubricating port valve is operated by its compressive action.
CONSTITUTION: Upon rotation of a shaft 2 coupled direct to a pump, an eccentric pivot block 11 mounted on the shaft 2 rotates. A piston 13 in contact with an outer periphery of the eccentric pivot block 11 reciprocates according to actions of a spring 17 and the eccentric pivot block 11. A reciprocation of the piston 13 is translated into an expansion work on internal capacity of a cylinder 14, giving a stroke of suction, compression and exhaust. If a pump comes to stop during compression stroke of the piston 13, a pressure in a space 28 is absorbed in the interior 9 of the pump by way of a space 30, an oil hole 29 is closed by a valve 23, and a counterflow of external oil in the interior 9 of the pump is prevented. Only a quantitative oil absorbed in the space 28 is fed in the interior 9 of the pump.
