Abstract

In a control for a motor vehicle change speed gear wherein movement of a shift lever 1 selects a number of gear ratios, additional ratios are controlled by a valve plate 20 rotatable with a knob 2 relative to the shift lever 1 to selectively supply pressure air to a ratio shifting servomotor 6. The servomotor 6 comprises two axially arranged cylinders 7, 8, each having a piston 9, 10, the rod 11 of one being connected to a fixed abutment 13 whilst the rod 12 of the other moves a shift lever 16 between low, high and neutral ratio positions. A recess 25 in the valve plate 20 selectively connects a pressure supply line 19 to servo lines 4 whilst a recess 24 connects a vent line 23 to other servo lines 4. The knob 2 is held in the ratio positions by a spring-pressed detent 27. A valve (C) (Fig. 9, not shown) in the pressure air supply line 19 is only opened to supply pressure air to the valve 20 when a main clutch-pedal (A) is depressed to disengage the clutch. The servo-cylinders 7, 8 are exhausted locally through valves H, Fig. 11. Each valve 11 comprises a valve element H10 which closes an exhaust port H8 when pressure air is supplied from the control valve 20 to the valve inlet H3. The air passes round a flexible skirt H12 of the valve element and through an outlet H5 to the servo 6. When the control valve 20 connects the inlet H3 to vent the valve element H10 is lifted off the exhaust port H8 to vent the servo.
