Abstract
An evacuation valve for a metering device for a liquid medium is disclosed. The valve includes a seal holder having a chamber formed therein and a seal. An elastomeric material fills the chamber to form the seal. The seal includes a smooth, flat sealing surface located above the seal holder. The inclusion of a lip in the chamber retains the seal; a non-circular lip prevents rotation of the seal.
