Abstract
To isolate shock deburring valve units in a shock deburring system and prevent back-flash or backfire during operation of the deburring system, and absorb thermal and pressure shocks exerted against the deburring valves--which, in operation, are closed--at least one of the valves is separated from the mixing chamber where the explosive force arises by a connecting line which is long enough and encloses therein a volume of the respective gas which is such that under the pressure due to an explosion in the mixing chamber, the gas can compress within the respective connecting line to thermally isolate the valve from the chamber and provide a compressible thermally isolating shock cushion for the respective valve to protect the valve against thermal damage and shock. Preferably, the valve is constructed to use a resiliently deformable sealing material between a portion of the valve bore and the valve sleeve in which a cylindrical insert is located so that pressure transferred to the closed valve will result in inwardly directed radial pressure upon deformation of the deformable substance over the sleeve and against the cylindrical projection to provide a reliable seal and, should damag…
