Abstract
A depressurisation valve () for a pressurised cooling circuit, comprising a main valve (), a pilot line () fluidically coupled to the inlet () and closable by a first control valve (), the first control valve controlled by pressure at the inlet to open above a low pressure threshold, a valve dome () containing a first piston () coupled to the main valve, the valve dome being fluidically coupled to the pilot line, wherein in normal operation, pressure on the first piston urges the main valve into the closed position, and when the pressure in the coolant circuit is lower than the low pressure threshold, the first control valve closes to allow the main valve to open, when the pressure in the coolant circuit is higher than the high pressure threshold, a second control valve opens to transmit fluid pressure to apply a second force to the main valve opposing the first force to urge the main valve to the open position.
