Abstract
A rotary spool reversing valve is described which is operated in rotation by two parallel opposed push buttons. The spool is positioned in line with the incoming air passage permitting incoming air to flow axially through the spool directly to forward or reverse motor ports with a minimum of pressure loss. Thumb operation of the push buttons in a pistol grip tool permits convenient one hand operation with simple molded mechanisms providing economy and ease of operation.
