초록 ▼

A hammer of the type having an impact tool driven by pressurized fluid has a hammer body portion with a closed rearward end and an open forward end and a piston longitudinally movably housed within the hammer body portion for striking a tool mounted at the open forward end of the hammer body portion, to thereby impact an object with the tool. The hammer has a fluid valve housed within the closed rearward end of the hammer body portion rearwardly of the piston and in communication with a source of high pressure fluid for driving the piston. The fluid valve has a valve body portion defining an interior chamber and a continuous exterior side wall, and a longitudinal opening in communication with the interior chamber. The valve body has a first body portion and second body portion which is identical to the first body portion and positioned longitudinally in relation thereto within the closed rearward end of the hammer body portion. The first valve body portion and the second valve body portion each have at least one open-sided transverse channel extending from the continuous, external side wall of the wall to the internal valve chamber to thereby simplify and facilitate manufacture of the valve body, and the longitudinal opening and the open-sided transverse channels permit access of pressurized fluid through the valve chamber between the closed rearward end of the hammer body portion and the piston to direct the flow of pressurized fluid entering the valve.

A hammer of the type having an impact tool driven by pressurized fluid, the hammer comprising: a hammer body portion having a closed rearward end and an open forward end, a piston longitudinally movably housed within the hammer body portion for striking a tool mounted at the open forward end of the hammer body portion, to thereby impact an object with the tool, and a fluid valve housed within the closed rearward end of the hammer body portion rearwardly of the piston and in communication with a source of high pressure fluid for driving the piston, the fluid valve having a valve body portion defining an interior chamber and having a continuous exterior side wall, a longitudinal opening in communication with the interior chamber, wherein the valve body has a first body portion and second body portion which is identical to the first body portion and positioned longitudinally in relation thereto within the closed rearward end of the hammer body portion, the first valve body portion and the second valve body portion each having a face surface and a back surface, each face surface having an identical formed well area therein, the identical formed well areas being disposed facing and coaxial to one another, thereby defining the valve interior chamber when the valve is in normal operating position, the first valve body portion and the second valve body portion each having at least one open-sided transverse channel extending from the continuous, external side wall of the wall to the internal valve chamber to thereby simplify and facilitate manufacture of the valve body, and the longitudinal opening and the open-sided transverse channels permitting access of pressurized fluid through the valve chamber between the closed rearward end of the hammer body portion and the piston to direct the flow of pressurized fluid entering the valve to drive the piston forward and back in the hammer body portion to strike and then return to pre-striking position repeatedly in rapid succession, for causing firing and return of the piston to its pre-firing position as a valve disc moves between a first disc position and a second disc position in the internal chamber, and a disc movably contained within the internal chamber.
