なしたことを特徴とする油圧ポンプ。The lower part of the lid has a flexible auxiliary tank and a motor protruding from the top, and the lower part of the lid is filled with hydraulic oil and sealed to keep the pressure inside the oil tank constant at all times. A plurality of cylinders are installed in the lid so that they face each other in the horizontal direction so that a part of them is exposed, and open into the mutual oil tank. One of the inner chambers has an on-off valve placed under the action of a spring and a discharge passage, and the other front chamber has a suction hole that opens into the oil tank, and the plunger can be slid freely. When fitted, the discharge passages of both cylinders are made to communicate with each other so that they are led to one discharge hole, and suction is caused by alternate sliding of the plungers by rotation of a cam provided between the two opposing plungers. A hydraulic pump characterized by being compact and capable of generating high pressure by performing a pumping action by opening and closing a hole and by the action of an on-off valve.
