Claims

[Scope of utility model registration request]

A hydraulic chamber and a pressurizing chamber are defined by a flexible membrane, and the hydraulic chamber is connected to a passage of a liquid supply pump and a liquid drainage passage,
On the other hand, in a pressure feeder structure where the pressurizing chamber is connected to the supply inlet and outlet, the tip of the support bar is fixed to the inner surface of the flexible membrane, and the base of the guide bar is fixed to the wall of the hydraulic chamber for support. A pumping machine structure that supports a bar in a slidable manner and is characterized in that a flexible membrane around a fixed part of the support bar is formed to have a thickness that gradually increases from the front to the front thereof.
