Manifold having integrated pressure relief valve |
摘要 |
Apparatus for dispensing a liquid includes a manifold having a high pressure passageway adapted to be coupled to a source of the liquid and to deliver the liquid at an elevated pressure to a dispenser. The manifold further includes a low pressure passageway for exhausting pressurized liquid from the high pressure passageway. A pressure relief valve is coupled between the high pressure passageway and the low pressure passageway. The pressure relief valve has a valve member mounted for movement relative to a valve seat. One side of the valve seat defines a high pressure side in communication with the high pressure passageway and another side of the valve seat defines a low pressure side in communication with the low pressure passageway. A dynamic seal engages the valve member on the low pressure side and prevents leakage of the liquid from the low pressure side.
