せた構成を特徴とする電気式増圧器。 The drive part is an electric motor with a reducer brake, and the output shaft is a screw or ball screw, and the nut or ball screw nut and oil compression cylinder that are screwed together in the housing and move forward and backward are pressed from the back side. A coil spring is stretched between the flange body provided on the back side of the push rod, and the cylinder is pressed by pressure corresponding to the amount of compression of the coil spring, and the side of the flange body opposite to the coil spring. This is an electric pressure intensifier characterized by a structure in which a return spring is stretched between the inner wall of the housing and the inner wall of the housing.
