Abstract:
A valve includes a valve housing body extending along a central longitudinal axis (X) between a first end and a second end. The valve housing comprises a first chamber at said first end comprising a gas inlet for receiving a gas and a second chamber at said second end having a plug provided at said second end, and an inter-chamber passageway connecting said first chamber to said second chamber. The valve further comprises a gas outlet provided in said inter-chamber passageway, and a piston provided in said inter-chamber passageway. The piston is movable between a first position wherein said outlet is blocked by said piston and a second position wherein said outlet is not blocked by said piston. The plug has a ventilation passageway extending therethrough. The valve has bypass channel configured to fluidly connect the first chamber to said second chamber and is not aligned with the ventilation passage.
