ENHANCED LOW NOISE, LOW LEAKAGE RELIEF VALVE

An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing.

Zusammenfassung:An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing. This is accomplished by providing an additional valve stem holder that acts as a stem holder through which at least part of the tube portion of the valve member extends, with the stem holder instead of the valve member tube being located adjacent to the bore of the machined housing. The stem holder does not need to be subject to the anodizing process, and therefore a tight tolerance between the valve member and stem holder provides adequate leakage control, and the anodizing process applied to the machined housing otherwise is separated from the location where leakage tolerance is critical.
