HYDRAULIC ASSEMBLY FOR DRIVING AND CONTROLLING OF SMALL HYDRAULIC UNITS, ESPECIALLY OF BRAKE CYLINDERS AND CLUTCH CYLINDERS OF A FORESTRY WINCH

摘要

A hydraulic assembly for driving and controlling small hydraulic units, such as hydraulic cylinders of a brake and/or clutch of a forestry winch, is disclosed. The hydraulic assembly includes a means for establishing and also maintaining a pre-determined pressure of a hydraulic media. The hydraulic assembly is characterized by as low as possible hydraulic loss. Also, a quantity of hydraulic media required for a regular operation and maintaining the pressure within the hydraulic assembly is as low as possible.
