Abstract:
1. A valve system comprising: a housing containing a fluid inlet channel and a fluid outlet channel, wherein the fluid inlet channel and the fluid outlet channel are connected by a through-hole; and an elastomeric valve boss having a hollow elastomeric cylindrical portion forming an interior cavity and a head portion, the cavity including an opening at a first end of the elastomeric cylindrical portion opposite the head portion, the elastomeric cylindrical portion extending concentrically through the through-hole such that, under static conditions, a rim on an underside of the head portion of the valve boss forms a valve seal face that maintains contact with a rim of the through-hole preventing fluid flow through the through-hole, the rim of the through-hole forming a valve seat, the valve boss having an open position wherein the elastomeric cylindrical portion is axially stretched by application of a force to an interior surface of the cavity to displace the valve seal face from the valve seat to form a gap therebetween resulting in a fluid connection through the through-hole between the fluid inlet channel and the fluid outlet channel.
