Abstract

The present invention relates to hydraulic device, and is especially one hydraulic cylinder controlled hydraulic transformer. The hydraulic cylinder controlled hydraulic transformer consists of hydraulic transformer member and controller connected together, the hydraulic transformer member consists of mainly casing, back end cap, front end cap, main shaft, cylinder, fluid distributor, central shaft, link rod and plunger; and the controller in the joint between the back end cap and the casing of the hydraulic transformer has one three-position-four-way solenoid change valve connected to the two-action hydraulic cylinder, hydraulic oil source and oil tank by means of oil path. The two-action hydraulic cylinder and the fluid distributor forms the ydraulitc cylinder controlling and driving structure to output relatively great force to control the rotation of the fluid distributor, and the solenoid change valve controls the reciprocation of the hydraulic cylinder.

Description

Technical field

[0001] The invention relates to a hydraulic component, in particular to a hydraulic transformer controlled by a hydraulic cylinder. Background technique

[0002] The constant pressure network secondary adjustment technology developed in recent years has improved the flexibility and efficiency of the hydraulic system, and has attracted worldwide attention. However, this technology has certain defects that restrict its application in the hydraulic field. Because, in driving the rotating load, the driving of the rotating load can be realized by adjusting the adjustment mechanism of the variable hydraulic motor; but there is no good solution for driving the linear load with different load pressure requirements. In response to this problem, people designed a new type of hydraulic device-hydraulic transformer, and continued to improve and optimize the hydraulic transformer to further adapt to actual needs. The publication number CN1455119A, the name "a hydraulic transfo...
