Integrated valve block

Abstract

The invention discloses an integrated valve block and belongs to the field of hydraulic technology. The integrated valve block comprises a valve body (200) provided with an inner cavity (201). Through holes are formed at two ends of the inner cavity (201) of the valve body (200). Five annular through holes are radially formed between the outer wall face of the valve body (200) and the inner cavity. A valve element (220) is nested into the inner cavity (201). Four coaxial cylinders with the same cross section are disposed at intervals in the axial direction of the valve element (220). The four cylinders of the valve element (220) are matched with the inner cavity (201) to form a zero-openness two-position four-way reversing valve. Compared with the prior art, the integrated valve block is free of an electric control system and simple in system.

Description

technical field

[0001] The invention belongs to the technical field of hydraulic pressure and relates to a supercharging device, in particular to a supercharging cylinder, an integrated valve block and a supercharging device thereof. Background technique

[0002] The principle of the pressurized cylinder in the general sense is to increase the proportional output of the input hydraulic oil according to the difference in the effective area of ​​the piston and the plunger. The boost ratio is equal to the inverse ratio of the piston area. This booster cylinder only performs one-stage booster conversion, and the booster ratio is a linear proportional relationship between the radial area of ​​the piston and the plunger, and does not fully utilize the space volume of the booster cylinder for boosting. In order to achieve two-way continuous supercharging, the following double-acting reciprocating superchargers have emerged, such as electromagnetic reversing valves, etc. However, ...
