AIRTIGHT GASKET FOR PNEUMATIC TOOL

摘要

An airtight gasket for a pneumatic tool including an airflow regulation portion, an air intake passage to direct high pressure air into the airflow regulation portion and a pneumatic motor to receive the high pressure air from the airflow regulation portion and generate spinning. The airflow regulation portion includes a regulation valve which contains a flow directing vent corresponding to the air intake passage and a recess surrounding the flow directing vent. The airtight to gasket is clamped between the regulation valve and air intake passage, and includes a base located in the recess, a through-hole located on the base to channel the high pressure air into the flow directing vent, and an airtight convex ring surrounded the through-hole and extended integrally from the base towards to air intake passage.
