Abstract

A pressure relief valve comprises a housing with a support member 1 having an inlet aperture 3 and an O- ring seal 2 positioned around same. A flexurally resilient diaphragm plate 4 seals against the O-ring 2 with the edge portion of the plate held by the housing. The plate has apertures therethrough towards the outside of the O-ring whereby excess pressure at 3 lifts the plate and causes venting through the apertures to the outlet 6, until the pressure reduces to allow the plate to reseal. <IMAGE>
