Abstract
A steering system including a first member, and a second member movable relative to the first member, and a hydraulic assistance device comprising a valve portion including a first valve port, and a second valve port. The valve portion communicates with a fluid pressure source and a hydraulic cylinder assembly, and is connected to the first member and movable in response to movement of the first member relative to the second member for selectively supplying fluid from the fluid pressure source to the second valve port and for transmitting fluid to the hydraulic cylinder assembly from the first valve port in response to movement of the first member in one direction relative to the second member, and for supplying fluid from the fluid pressure source to the first valve port and for transmitting fluid to the hydraulic cylinder assembly from the second valve port in response to movement of the second member in the opposite direction relative to the first member. The hydraulic assistance device further includes a slave hydraulic cylinder assembly communicating with the first valve port and the second valve port, connected to the second member, and movable in response to movement of the first member relative to the second member for supplying fluid to the first valve port and receiving fluid from the second valve port in response to movement of the first member in the one direction relative to the second member, and for supplying fluid to the second valve port and receiving fluid from the first valve port in response to movement of the first member in the opposite direction relative to the second member.
