[origin: US6298968B1] A transmitter for hydraulic control controlled by a controlling member including a hydraulic chamber having a piston mounted thereto by means of a joint. The hydraulic chamber defines a pressure chamber with variable volume connected to a hydraulic line. A reservoir is connected to the pressure chamber via a passage. A mechanism for preventing the fluid from returning to the reservoir and a mechanism for transmitting the control member movement to the piston is also provided. The hydraulic chamber is extends along its axis defining a reserve volume and is adapted to receive the piston and containing hydraulic fluid up to a level sufficient for the joint to be immersed therein.
