HAND PUMP WITH PRESSURE RELEASE MECHANISM AND SYSTEM OF USE
摘要
A hand pump includes a pumping system having a primary pressure chamber and a valve control assembly. The valve assembly includes a vent passageway in communication between the primary pressure chamber and ambient and a valve seal assembly having a seal and a seat. A biasing mechanism biases the seal against the seat to obstruct fluid or gas passage in the vent passageway to ambient. A traction device may be fluidly coupled to the hand pump system.
