Device with co molded closure one way valve variable volume storage chamber and anti spritz feature and related method

摘要

pA device has a first part with a valve seat and storage chamber and a second part with a flexible valve cover and actuator. The flexible valve cover and valve seat form a normally closed valve seam there between. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam./p
