Abstract

PURPOSE: To reduce the prime mover load by constituting an oil hydraulic pump so that when the oil pressure in a pressure accumulator reaches a given value, the oil pressure in a pump chamber also shows a similar value, and the pushing-up force of said oil pressure for a plunger balances with a spring, keeping the plunger in the vicinity of the upper limit by a tappet.
CONSTITUTION: Formed in a pump main body 70 are a spring chamber 75 housing a spring 82 which applies a given spring force to a plunger 79 slidably passed through the partition wall between a pump chamber 76 communicating with an oil tank 30 and a pressure accumulator 31 through a suction valve 86 and a discharge valve 88, toward the side of a tappet 78 which has a diameter smaller than the plunger 79 and is driven by a driving member 65, and an actuating chamber 77 housing driving members such as the pump driving shaft 65 and the like. In addition, the tappet 78 is slidably passed through the partition wall between the pump chamber 76 and the actuating chamber 77 and separatably contacted with the plunger 79. Thereby, the oil pressure in the pressure accumulator 31 reaches a given value, the oil pressure in the pump chamber 76 permits the plunger 79 to be kept in the vicinity of the upward limit by the tappet 78. Accordingly, the prime mover load connecting with the driving shaft 65 can be largely reduced.
