Scavenger valve assembly

Abstract

A poppet scavenger valve includes multiple cages for multiple poppets, permitting better control of the spacing of the assembly, facilitating maintenance and permitting better fluid flow through the cage structure. A spacer or lift plate may be positioned between the cage and the seat for defining a flow control device for accurately setting and controlling the valve flow. Each cage component is mounted on the lift plate and is trapped between the plate and the seat. Alignment pins are provided to assure proper alignment between the cylinders and the mated counter bores in the cages. The stroke, or valve flow, can be controlled by adjusting the height of the lift plate, without any alteration to or modification of the cage. Multiple cage configurations are possible, including cages for supporting any array of poppets from a grid to a longitudinal assembly. Each cage is adapted for supporting any multiple of poppets, including single poppet cage systems where applicable. Each of the plurality of cages in the valve system may be customized to provide clearance for external components and for other uses, as necessary.
