Press the abrasion of piston core.
Preferably, second level concave station sets O-ring a, Gourde(G) ring is set on the outside of O-ring a, Gourde(G) ring and O-ring a cooperate, double
Protection protection high pressure piston core again, lowers the abrasion of high pressure piston core and high pressure piston lid.
Preferably, O-ring b, during high pressure piston core moves back and forth, O-ring b are set inside the piston core of high-pressure side
Stablize coefficient of friction, while mitigating high pressure piston core inner through-hole and the abrasion of high pressure piston lid.
Preferably, high pressure piston cap assemblies include high pressure piston lid and piston brass circle b, and high pressure piston lid outer ring sets concave station
B, piston brass circle b are located on concave station, and piston brass circle b is protruded than high pressure piston core cap, lower the abrasion of high pressure piston lid.
Compared with traditional technology, the utility model generate beneficial effect be: by high-pressure piston rod low-pressure piston with
High pressure piston is linked to be an entirety, ensure that high pressure piston and low-pressure piston concentricity and verticality, it is therefore prevented that high pressure piston is anti-
Abrasion deformation during multiple operation；By setting adjustment gasket between high pressure piston and high pressure piston lid, reduce between the two
Gap improves airtightness.
