Problems solved by technology

[0004] (1) Because the stroke reversing valve uses steel ball positioning and chains to maintain two positions, and controls the booster cylinder to move in different directions, the structure is complex and the processing is difficult
And the positioning of the steel ball is easy to fail, the chain is broken, and the stroke control reversing valve will be in the floating position, that is, the booster cylinder stops moving, so this control method is unreliable;
[0005] (2) The overall structure is complex and the processing cost is high

Abstract

The invention provides a double-acting reciprocating type hydraulic supercharger. The supercharger is provided with an oil inlet, a first working oil port, a second working oil port, an oil return port, a high-pressure oil outlet, a reversing valve element, a left spring, a right spring, a piston, a left plunger, a right plunger, a first one-way valve, a second one-way valve, a third one-way valveand a fourth one-way valve. The double-acting reciprocating type hydraulic supercharger is simple in structure and capable of achieving high-frequency supercharging.

Description

technical field [0001] The invention relates to a booster, in particular to a double-acting reciprocating hydraulic booster capable of reliable automatic and continuous boosting. Background technique [0002] The hydraulic booster is an ultra-high pressure hydraulic component that amplifies the hydraulic pressure by using the principle that the two ends of the piston have different acting areas and the same force, and the hydraulic booster can increase the low pressure to 200MPa and above. Hydraulic boosters can be divided into three types: single-acting single-stroke booster, single-acting reciprocating booster and double-acting reciprocating booster. Since the single-acting single-stroke supercharger can only move in one direction, the stroke is limited, the output flow is limited, it cannot achieve continuous supercharging, and its application range is narrow. The single-acting reciprocating supercharger can achieve continuous supercharging, but it can only supercharge o...
