Abstract

See full text

A hydraulic control system comprising master and slave pressure units having pistons and which are filled with fluid. The master piston is connected to a control lever, while the slave piston is connected to an object to be controlled such as a clutch lever on a marine engine. Hoses so interconnect the master and slave pressure units that movement of the control lever moves the master piston and causes fluid to act on the slave piston to cause the piston to move and thus move the clutch lever. A port is formed in the casing of one of the master or slave pressure units. This port is formed to allow communication between a reservoir of fluid and the casing. Given that chambers are formed on either side of the pistons within their respective casings, the port is so arranged that each of these chambers is placed in fluid communication with the reservoir at least once during the stroke cycle of the master piston (i.e., from begining to end and back to the beginning of the stroke).
