Abstract:
A tip valve for a pneumatic tool includes a first valve member having a bore with a central axis and defining a valve seat about the bore and a second valve member having an engaging surface engageable with the valve seat to form a substantially fluid-tight seal therewith. A stem is coupled to the second valve member and extends through the bore, with at least a portion of the stem being offset from the axis, and a valve operating member is coupled to the stem for movement between a closed position wherein the second valve engages the valve seat to close the bore and an open position wherein the second valve member is tilted from the valve seat to open the bore. A spring urges the second valve member and the valve operating member to the closed position. In one embodiment, the stem is bent and in another it is straight but eccentrically mounted on the second valve member.
