    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: An overspeed shutoff device for use in a rotary pneumatic tool is disclosed. The device is operable to shut off air supply to the motor on failure of its governor to function properly in preventing overspeeding of the motor. The device includes a valve closing plate positioned in the path of air flow to the pneumatic motor, just upstream of an inlet port for passage of air into the motor. In normal operation of the tool the valve plate, which rotates with the motor drive shaft, is retained in a position spaced from the air inlet port by a locking mechanism engaging the drive shaft of the tool to prevent axial movement therealong. The plate locking device comprises a cantilever mounted spring wire in engagement with a groove in the drive shaft and a centrifugally responsive weight operably connected to disengage the wire from the groove in response to the attainment of a predetermined rotary speed. Upon failure of the main governor of the tool and consequent acceleration of the motor to such predetermined speed, the wire is disengaged from the shaft groove and the air pressure drop across the valve inlet port causes the closure plate to move toward and cover the inlet port, thereby stopping the flow of air to the motor.

    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.

    Abstract: An adapted elastomer compound, in which the adaptation is based at least in part on load performance data of a rotor/stator test coupon as evaluated on a test apparatus. The test coupon's stator section includes the original elastomer compound before adaptation thereof. The test apparatus includes a motor, a brake, and at least one sensor disposed to evaluate load performance data of the test coupon. The load performance data is the product of the process comprising the steps of: (a) rotating either the rotor section or the stator section on the test apparatus, wherein such rotation section actuates corresponding rotation of the other of the rotor section and the stator section; (b) applying a braking torque to the actuated rotor section or stator section; and (c) responsive to step (b), evaluating load performance data of the test coupon.
