  • Patent number: 8528659
    Abstract: A power tool has a housing, a pneumatic rotation motor supplied with pressure air via an inlet passage, an outlet passage connecting the motor to an exhaust air discharge, and a speed governor for controlling the pressure air flow through the inlet passage responsive to the motor speed. The outlet passage includes a first outlet duct and a second outlet duct extending in parallel between the motor and exhaust air discharge, and an exhaust valve which controls exhaust air flow through the second outlet duct. The exhaust valve is spring biased toward a closed position and shifted to an open position by an activator which is exposed to the air pressure in the inlet passage downstream of the speed governor and which shifts the exhaust valve to the open position at pressure levels above a certain pressure level in the inlet passage downstream of the speed governor.

  • Patent number: 8439124
    Abstract: A pneumatic power tool with a housing assembly, a pneumatic motor assembly, an output member, and a trigger assembly. The housing assembly has a body, a cap member and a gasket assembly. The body defines a motor cavity and an inlet manifold. The cap member defines an air inlet port. The gasket has a first portion being a band formed of a compressible material and a second portion formed of a porous material. The band of the first portion is sealingly abutted against the body and cap member. The pneumatic motor assembly is received in the motor cavity defined by the body. The output member is driven by the pneumatic motor assembly. The trigger assembly is coupled to the housing assembly and is operable for selectively operating the pneumatic motor assembly. Pressurized air received into the air inlet port is filtered by the second portion of the gasket assembly and flows into the inlet manifold when the pneumatic motor assembly is operated. A related method is also provided.

    Abstract: A bypass assembly varies the hydraulic motor revolutions per minute (rpm) of a hydraulically driven tool, such as a wrench or a drill. This controls the torque of a driven mechanical mechanism, such as used on an impact wrench. The tool includes a body having a supply channel capable of being connected a source of fluid, a bypass spool channel in fluid communication with the supply channel, and a return channel in fluid communication with the bypass spool channel via a port and in fluid communication with the source. A bypass spool seats in the bypass spool channel. The bypass spool can be rotated to three discrete positions within the bypass spool channel to provide three different settings of revolutions per minute (rpm) of the gear motor.
