Steering gear for motor vehicle has annular hydraulic seal in dynamic sealing contact with toothed rack and defines fixed end of hydraulic fluid chamber of variable volume extending from piston to seal
The steering gear comprises a toothed rack(118) attached to a piston(160) housed in a hydraulic power cylinder(116) and extending outwards from the cylinder's open end(172). An annular hydraulic seal(164) is in dynamic sealing contact with the rack and defines a fixed end of a hydraulic fluid chamber(173) of variable volume extending from the piston to the seal. A housing section(114) is fitted to the power cylinder and supports the seal at a point opposite the open end of the cylinder, and defines one end section(191) of the fluid chamber.
