Abstract
A pressure responsive, fluid flow control valve, particularly for a truck gear box shifter, for controlling flow of one fluid such as air in response to the pressure of another fluid such as liquid. The valve comprises a body 12 with a longitudinal passage 14 containing a valve seat 34 cooperating with a ball valve 36 to control communication between an inlet 18 from an air source 20 and an outlet 24 to the gear box shifter. The position of the ball valve is controlled by a rod 58 the position of which is controlled by a spring 70 and the pressure of the hydraulic fluid in the clutch slave cylinder applied to a piston 50. When the ball is seated on the seat the gear box shifter is vented through passages 60, 60' in the rod and a vent passage 26. Thus the gear box cannot be shifted except when the clutch pedal is depressed. <IMAGE>
