A two-way valve (20) has a poppet valve (50) displaceably disposed in a bonnet (28) for selectively opening and closing a communication passage (48) between primary and secondary ports (22), (24), and a resilient member (82) disposed in a diaphragm chamber (80) defined between the bonnet (28) and the poppet valve (50) and resiliently deformable for dampening a load applied to a diaphragm (58) of the poppet valve (50) which is exposed to the communication passage (48). <IMAGE> |
