Excess pressure protection for vehicle liquid petroleum gas tank, comprises means of measuring tank pressure and sending signal to electronic module which detects rate of rise exceeding threshold

摘要

A vehicle fuel tank (1) containing liquid petroleum gas (2) is protected from an extremely rapid rise in pressure by a pressure measuring unit (4) which sends a pressure signal to an electronic module (5). The electronic module compares the rate of rise of pressure with a preset threshold and if necessary sends an electrical signal to a (3)
