摘要：
A rotary spool reversing valve is operated in rotation by two parallel opposed push buttons (25, 30). A spool (10) is positioned in line with an incoming air passage (4) permitting incoming air to flow axially through the spool directly to forward or reverse motor ports (20, 21) with a minimum of pressure loss. Thumb operation of the push buttons in a pistol grip tool permits convenient one hand operation with simple moulded mechanisms providing economy and ease of operation.
