An automatic reversing control for fluid operated rotary tools which is responsive to a fluid pressure increase in a motor inlet passage to cause a reversal of the direction of motor rotation. A shiftable spool valve is biased to reverse the motor by pressure fluid acting on the valve spool. A sprin...

description	An automatic reversing control for fluid operated rotary tools which is responsive to a fluid pressure increase in a motor inlet passage to cause a reversal of the direction of motor rotation. A shiftable spool valve is biased to reverse the motor by pressure fluid acting on the valve spool. A spring biased check valve is operable to valve biasing fluid to actuate the spool valve in response to sensing a predetermined fluid pressure in the motor inlet passage. An operator actuated start valve is disposed between the reversing valve and the motor to initiate and control the operating cycle of the tool.
