| description | A tip valve assembly for a pneumatic tool with an integrated wear surface. The tool has a portion with an air channel bore housing. The tip valve assembly includes a first valve member having a bore and defining a valve seat about the bore and a second valve member capable of forming a seal with the valve seat. The second valve member can be tilted from the valve seat to permit air flow through the bore of the first valve member. The wear surface projects over only a portion of the cylindrical wall in the bore housing in conjunction with an edge of the second valve member that can be tilted farthest, so the second valve member does not contact the cylindrical wall of the bore housing. As an anti-rotation feature, the second valve member may have an outer periphery with a shaped recess between lobes. The first valve member may have a complementary shaped integrated wear surface disposed in the recess so the second valve member moves without internally rotating as well as not contacting the cylindrical wall of the air channel bore housing. |
