The first groove surrounds to form a main channel with corresponding second groove when conjunction, and the diameter of the madial wall of main channel along main channel is inside
For spill at an accommodating cavity, accommodating cavity is interior to be equipped with elastic sealing element, is equipped with the accessory channel being connected with main channel in lower body, uses
Push elastic sealing element towards movement outside main channel in entering for high pressure medium in main channel.
The upper body is equipped with a pressure release passage, and the lower end of pressure release passage is connected to main channel, the upper end of pressure release passage
Vertically run through the upper surface of upper body.
The pressure release passage is equipped with a dismountable plug.
The position inscribe of nearly lateral wall forms a conical surface on the lower face of the lower body, and the conical surface is equipped with and accessory channel
The opening being connected.
The elastic sealing element includes columnar inlay and the elastic layer that is covered on inlay outer surface, the elastic layer
Vulcanize with inlay integral type and fixes.
The cross-sectional diameter of the inlay is more than the diameter of main channel and the diameter less than accommodating cavity.
After using the above structure, a kind of piston block of booster pump of the invention is compared with prior art with following excellent
Point：First, when one lateral pressure of the lower body of piston rises, high pressure is entered by accessory channel and pushes sealed elastic in main channel
The sealing of piston and piston cylinder is realized in part expansion, and with the rising of pressure, the directly proportional rising of elastic sealing element pressure, therefore
The sealing pressurize of piston can be realized when transient state reaches super-pressure, therefore can reach transient state superelevation by conventional booster pump
The purpose of pressure.
