Description

technical field

[0001] The invention relates to a fluid booster, in particular to a fluid booster which is powered by gas or liquid and is suitable for high pressure or super high pressure. Background technique

[0002] Traditional fluid pressurization uses purely mechanical push-push plunger method or single-stage pressurization uses two different piston areas similar to the Pascal principle of a jack. The pressurization is limited by the single-stage compression ratio to produce a high-pressure or ultra-high-pressure fluid pressurization. It is difficult to achieve. Other reciprocating booster reversing controls use a trigger mechanism similar to a travel switch. The setting of multiple links is likely to cause reliability problems and complex structures. Traditional fluid reversing control valves usually use cylindrical movement along the axis to switch It is difficult to realize the structural characteristics of the control valve by using double spools or more spools in ...
