Abstract

A rollover mechanism (3) for a pressure valve (1) is disclosed which is ideally adapted for use on mobile petrol tankers and other tankers for volatile liquids. The valve (1) comprises a valve seat (32) and a sealing means (18) which can be urged against the valve seat (32) to form a seal and prevent any fluid within the tanker from escaping through the valve (1) in the event of a rollover. Such valves (1) allow for pressure release therethrough under normal operating circumstances as fluid within the tanker often evaporates and pressure within said tanker can increase. The inventive valve (1) comprises a pendulum (10) mounted at an intermediate point along its length and having a pendulous weight (8) at one end and an arcuate contact pad (4) at the other. A float arrangement (37) for such a rollover valve (1) is also disclosed wherein a feed tube (36) is connected to the valve (1) beyond the valve seat (32) so that pressure can still be released through the valve (1) even when it is closed as a result of a rollover and the fluid pressure.
