摘要： The present invention provides a reciprocating pneumatic tool mechanism, including a casing, pneumatically-operated control module, control switch, actuating module and vibration-absorbing member. The plates of the actuating module are combined into a single body by the perforating locator. The periphery of the plates can be slidably abutted with the inner wall of the tank. The air inlet of actuating module is adapted air-tightly with air supply end of pneumatically-operated control module. At a front end of the actuating module, a protruding tube is screwed into a punch hole in front of the casing. The vibration-absorbing member includes a built-in buffer between actuating module and pneumatically-operated control module, and a front-mounted buffer between the front ends of actuating module and casing. With the invention, the vibration-absorbing members of reciprocating pneumatic tool is saved, improving the assembly efficiency, reducing assembly cost and volume with better economic efficiency.

摘要： A motor housing (11) is mounted in a handle body (10) so as to slide in the longitudinal direction. A tubular pipe (37) that can slide in a bore (38) of the body (10) projects from the back of the housing (11). Compressed air can be applied to the bore (38) through a switching valve (40). A piston (14) with a piston rod (17) can slide in the housing and a tool can be secured to its front end. A flutter valve (23) which alternatingly connects the bore (38) to the two cylinder chambers (27, 28) is built into the valve housing (22). The piston (14) alternatingly opens the connection to an outgoing air conduit (29-31). A pre-stressed spring (47) is set between the body (10) and the housing (11). In operation, the housing (11) oscillates out of step with the piston (14), so that their initial forces are largely compensated and no vibrations are transmitted to the handle body (10).

摘要： A reciprocating blade saw wherein the counterbalancing of the drive system includes the provision of two directly opposed and coaxial rams, one attached to the saw blade and the other having a mass equal to the first ram plus the blade, both being attached to a crankshaft by links which have their masses symmetrically distributed. The crankshaft is driven by a hydraulic motor, and all the masses are so matched that the saw is in balance at all speeds and can be operated at high speeds with minimal vibration. The saw is designed for use particularly in the meat industry.
