Mine working roller cutter machine fluid supply - involves pump with compartments linked separately to winch and gear chambers

摘要

Hydraulic-fluid-filled winch compartments and their lubricant- filled gear compartments are connectable to pumps for supply or removing The system is used on a mineral-extracting machine, esp. of the roller cutter type, in an underground mine. A pump fixed on the body of the machine has two compartments fitted with elements for fluid supply, one connectable only to the winch compartments and the other only to the gear compartments. There is at least one compartment filled with an element for pump drive, and influenced by a pressure-medium independent from the machine.
