摘要： In a valve arrangement in pneumatic impact motors (10), the housing (40) of a distribution valve has the form of a plastic bowl (46) which is flanged outwardly at the opening and the bottom thereof. A flat valve (50) is movable between the bowl bottom, which forms one valve seat (51) of the valve housing (40), and a bowl cover member (53), which forms the other valve seat (52). The bowl flanges (47, 48) define therebetween a groove which connects with a delivery channel (39) provided in the impact motor (10), this channel delivering compressed air to the flat valve (50) mounted inside the bowl (46). The bowl wall located between the flanges (47, 48) includes calibrated side openings (57, 58) which control the delivery of compressed air to respective valve seats (51, 52) on respective sides of the flat valve (50), this air delivery being an adapted and calibrated delivery.
