A control module (36) for a pneumatically operated fastener driving device (10) is constructed and arranged to be mounted with respect to a main frame portion of the device housing to be removable therefrom as a unit. The control module (36) includes a control module housing assembly providing an exhaust passage (76); a main valve (46) mounted for movement between opened and closed positions for opening and closing the passageway (76); spring structure (58) biasing the main valve (46) towards its closed position; exhaust seal structure (60) having an annular valve element (86) operatively associated with the main valve (46) for closing the exhaust passage (76) when the main valve is disposed in its opened position; and an actuating member (70) mounted for movement from a sealed position into an unsealed position for initiating movement of the main valve (46) to its opened position on actuation by a trigger assembly (102). <IMAGE> |
