Summary: | A gear shifting assembly for changing the speed positions of a transmission in an automotive vehicle has a hydraulic gear selector motor whose piston rod is normal to the piston rod of a hydraulic gear shifting motor. The cylinder of the gear shifting motor has two chambers one of which receives pressurized fluid to engage a selected gear and the other of which receives pressurized fluid to disengage a gear. The flow of fluid to and from the two chambers is controlled by a twin check valve which has two discrete one-way valves, one for each chamber and two flow restrictors each connected in parallel with a different one-way valve. When the pressure of fluid in one of the chambers rises to a preselected value, the corresponding one-way valve opens the other one-way valve to allow for practically unimpeded flow of fluid from the other chamber. |
