Abstract
This height adjustment system includes: a source of pressurized working fluid; several fluid pressure actuated wheel suspension units, each of which resiliently pushes a one of the wheels of the vehicle downwards with respect to the body thereof, according to the amount of pressurized working fluid supplied to it; a passage means for conducting supply of working fluid from the source to the wheel suspension units; several valve means, provided at intermediate points of the passage means, for controlling flow of working fluid therethrough; and a flow divider means which has an inlet and two outlets, one of the outlets being communicated to a first set of the wheel suspension units for a first set of the wheels of the vehicle and the other of the outlets being communicated to a second disjoint set of the wheel suspension units for a second disjoint set of the wheels of the vehicle. This flow divider is incorporated at an intermediate point of the passage means, provides a branch point of the passage means, and receives supply of pressurized working fluid at its inlet and divides this supply between its two outlets in a ratio which is substantially independent of the pressures at thes…
