Claims

[Scope of utility model registration request]

A cylindrical plunger body with a bottom, a hollow plunger that is slidably fitted into the plunger body with its upper end protruding, and forms a high pressure chamber between the plunger body and the bottom of the plunger body, and a high pressure chamber. a reservoir chamber that communicates with the chamber via a communication passage, a check valve provided in the communication passage that allows only the flow of hydraulic oil from the reservoir chamber to the high pressure chamber, and a bullet that biases the plunger in the direction of coming out of the plunger body. In the sealed hydraulic pump adjuster, the reservoir chamber includes a first reservoir chamber defined inside the plunger so that its volume can be changed by an inner diaphragm; a second reservoir which is communicated with each other and is defined so as to be variable in volume inside an outer diaphragm having one end fitted to the outer periphery of the open end of the plunger body and the other end fitted to the outer periphery of the upper end protrusion of the plunger; A sealed hydraulic hydraulic adjuster comprising a chamber and a chamber.
