Valve body charge lock
A method of regulating the disassembly of a component from a powered tool assembly that uses a pressurized fluid and a locking member that is in operative association or communication with the fluid is provided. The method comprises biasing the locking member into a locked configuration using the pressurized fluid, preventing movement of the component in a first predetermined direction.
1. A locking valve body assembly for use with a powered hammer assembly, the valve body assembly comprising:
a valve body that defines a void configured to contain a pressurized fluid and an axis of rotation, the valve body further including a top exterior surface and a drive structure on the top exterior surface for rotating the valve body from a locked configuration to an unlocked configuration about the axis of rotation; and
a locking member that is configured to be biased by the pressurized fluid into a locking configuration, preventing the rotation of the valve body about the axis of rotation.
2. The locking valve body assembly of claim 1 further comprising a retainer member that is configured to mate with a slot of a powered hammer assembly, wherein the locking valve body assembly is configured to prevent the retainer from being removed from the power hammer assembly along the axis of rotation.
3. The locking valve body assembly of claim 2 wherein the valve body and retainer member define a radial direction that is perpendicular to the axis of rotation.
4. The locking valve body assembly of claim 3 , wherein the locking member is configured to move in the radial direction.
