Abstract:
A dispensing valve for fluids comprising:a. a valve body comprising: (1) a first elongate channel having a rigid exterior wall defining a generally annular passage extending from a fluid inlet end to an actuator end; and (2) a fluid discharge outlet intermediate said inlet end and said actuator end; b. a valve port wall intermediate said inlet end and said discharge outlet, said valve port wall defining a valve port; c. a resilient valve seal moveable from a closed position in which said valve seal occludes said valve port to an open position in which said valve seal does not occlude said valve port; and d. a resilient actuator operatively connected to said resilient valve seal and operatively engaging said valve body so that said resilient actuator exerts a closing force on said resilient valve seal biasing said resilient valve seal towards said closed position, said resilient actuator exhibiting a nonlinear relationship between said closing force and displacement of said resilient valve seal from said closed position.
