ABSTRACT:
A hydraulic safety circuit which keeps a hydraulic motor supplied with fluid during the interval when the motor coasts to a stop following shut off of its source of driving fluid. The circuit includes a conduit extending between the motor outlet and the motor inlet, with a check valve arrangement which shuts off normal fluid flow from the motor outlet to the fluid reservoir when the driving pump is shut off, and which instead diverts the fluid through the above noted conduit back to the motor inlet. This permits fluid to circulate through the motor as the motor coasts to a stop, preventing dry coasting and consequent possible burnout. The invention is particularly applicable to a wood chipper, where a heavy rotor (containing wood chipping blades) is connected to the motor and causes the motor to coast for an appreciable interval after the pump is shut off.
