Pressurizing cylinder

Abstract

The invention provides a pressurizing cylinder, which belongs to the technical field of hydraulic pressure. The pressurizing cylinder comprises three parts, namely a primary piston (10), a secondary piston (20) and a cylinder tube (30), wherein the primary piston (10) is sleeved in an inner cavity of the secondary piston (20), the secondary piston (20) is sleeved in an inner cavity of the cylinder tube (30), and first pressurizing to hydraulic oil is completed due to mutual movement of the primary piston (10) and the secondary piston (20), and second pressurizing to the hydraulic oil is completed due to relative movement of the secondary piston (20) and the cylinder tube (30). Compared with a pressurizing cylinder in the prior art, the pressurizing cylinder provided by the invention has the advantages that the size is small, particularly, the radial size is greatly reduced, and the structure is compact.

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, ...
