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.
Claims24
A valve apparatus comprising:
- a housing including an inner space, an inlet, an outlet and a flow path for a fluid from the inlet to the outlet;
- a liquid for separating the flow that into first and second parts;
- and
- a baffle within the inner space for controlling entrainment of the liquid into a flow of the fluid along the flow path, wherein the baffle defines the flow path for the fluid and the flow path comprises a helical passage that winds about a longitudinal axis of the housing.
A valve apparatus comprising:
- a housing defining an interior chamber, the housing including:
- a first portion including first and second ports communicating with the interior chamber;
- a second portion spaced from the first portion along a longitudinal axis;
- and
- a third portion extending along the longitudinal axis between the first and second portions;
- a baffle disposed in the interior chamber, the baffle at least partially defining a helical fluid flow path between the first and second ports;
- and
- a volume of liquid disposed in the second portion of the housing, wherein the liquid separates the helical flow path into first and second parts, the first part of the helical flow path being in fluid communication with the first port, and the second part of the helical flow path being in fluid communication with the second port.
