摘要:
A spring clip retainer for securing a spool (20) in a bore (15) in, for example, a power tool (10), wherein the spool forms a swivel connection for a source of pressure fluid to operate and or control the tool. The clip has resilient tab means (40) for selected interconnection between the clip and the bore as a means for axial alignment in the bore and to permit the spool to rotate in the bore.
摘要:
A pressure fluid motor (1) having a regulator (30, 37) for regulation of output power of the motor, the regulator including a bypass of a selected portion of the supplied pressure fluid to the motor exhaust as a means of effectively reducing the available pressure drop across the motor and thereby its power output.

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.
摘要:
A power tool (1) wherein an integrated pressure fluid motor (13) is provided with a unitary motor cylinder 15 and back head (36) and an external co-operating porting surface for co-operating with a valve porting surface. Also provided is a co-operating front head plate (75) with concentric alignment lands for attachment of the motor and a power output device (19) such as a gear reducer or impact wrench.
摘要:
A planet gear frame assembly is so configured as to use common parts, whereby another assembly, having a different gear ratio, can be formed using the selfsame common parts. This is achieved by providing the assembly with a frame (12) and at least one pin (28) upon which the planet gear (14) is journalled, a washer (38) being engaged with the frame to retain the pin in place and axially-extending lands (42, 44), all formed at different offset distances from the pin centreline being provided on at least one end of the pin to engage the washer to prevents rotation of the pin relative to the frame. Only different gears and a different frame are required to form the other assembly having another gear ratio. Accordingly, stocking of discrete parts for the differing assemblies is greatly reduced.
