Filed:

Sep 29, 1982

Appl. No.:

6/426315

Inventors:

Arthur W. Gruber - Virginia Beach VA

Assignee:

The BOC Group, Inc. - Montvale NJ

International Classification:

B01D 3700

US Classification:

55520

Abstract:

A filter for removing particulate matter from a fluid stream, particularly from gas flowing through a pressure regulating valve. The preferred embodiment is a regular geometric pattern, such as a toroid, formed from a length of yarn. Preferably the yarn comprises continuous filaments of glass which are twisted together. When placed in a fluid line, such a filter has a large capacity for trapping and retaining small particles which disperse throughout the filter.

Abstract:

A pressure relieving device for use with gas flowmeters, pressure regulators and other fluid flow equipment is described. The device includes an O-ring and means for compressing and retaining the O-ring to provide a fluid-tight seal under normal operating pressure, but having a gap positioned such that the occurrence of an excessive pressure causes a portion of the O-ring to move into and through the gap to relieve the excessive pressure. A passage for enabling the fluid to contact the O-ring is sized to allow sufficient flow to relieve a fluid pressure substantially in excess of the normal operating pressure.
