Abstract
A valve apparatus includes a housing, which defines an interior chamber, a baffle disposed in the interior chamber, and a volume of liquid. The housing includes first, second and third portions. The first portion includes first and second ports that communicate with the interior chamber. The second portion is spaced from the first portion along a longitudinal axis. And the third portion extends along the longitudinal axis between the first and second portions. The baffle at least partially defines a helical fluid flow path between the first and second ports, and the volume of the liquid is disposed in the second portion of the housing.
