    Abstract: An over-speed safety device for a pneumatic rotation motor having a cylinder (10), a forward end wall (11), a rear end wall (12) with a pressure air inlet opening (21), a rotor (13), and an actuator (15) co-rotative with the rotor (13) and responsive to centrifugal action, and a valve lid (20) tiltable relative to a pivot axis (C) and shiftable between an open position and a closed position for controlling the airflow though the inlet opening (21), wherein the pivot axis (C) extends along a chord in relation to the rotor centre, and the actuator (18) comprises a cam surface (25) for camming engagement with the valve lid (20) for moving the latter in a radial direction toward the closed position. The valve lid (20) is supported by ridge positions (33, 34) on a seat surface (2) disposed around the inlet opening (21), and a wire spring (26) is arranged to retain and bias the valve lid (20) against the seat surface (32). The ridge portions (33, 34) are arranged to make the valve lid (20) perform an over-centre movement when shifted from open to closed position, thereby obtaining a bi-stable action of the valve lid (20) under action of the wire spring (26).

    Abstract: A rotary pneumatic tool includes an over-speed shut-off mechanism including a shiftable spring washer and flyweights for imparting a shifting force to the spring washer dependent on the speed of the tool. In the preferred embodiment, the spring washer is shifted by spherical balls restrained by cylindrical walls within a body affixed to the rotor in combination with the spring washer and spring members attached to the body. The spring rates of the spring washer and spring members predetermine the speed at which the over-speed mechanism becomes activated.

    Abstract: A powered rotary grinder including a vane-type fluid motor having a rotor supported within a housing. Pressurized fluid is admitted to the motor through a control valve to drive the rotor. A pivoted lever is engageable with the control valve and is actuated by flyweights attached to the rotor to regulate the speed of the rotor. The control valve includes normally latched, stored energy means which, when released, slams the control valve completely shut to cut off flow of pressurized fluid to the motor. A centrifugally actuated weight or weights interconnected with the rotor are operable to release the latched stored energy means should the rotor overspeed and the regulator fail to operate. In one embodiment, the weights include interengaged means which require that all the weights move radially outwardly of the rotor conjointly to effect release of the latched, stored energy means. This interengaged means insures that only centrifugal force can move the weights and that they cannot accidentally or unintentionally move to effect release of the stored energy means in the event, for example, the grinder is dropped or is otherwise struck with a sharp blow.
