Abstract

A compact four-way fluid flow control valve wherein an inlet port and three outlet ports are all disposed on the sidewall of a manifold. A valve core is rotatably disposed within the manifold, and has first and second core openings. Annular seals are disposed at blind portions of the sidewall of the valve core in non-circumscribing relation to the core openings and in abutting relation to the manifold. Rotation of the valve core with respect to the manifold provides selected fluid flow to any of the outlet ports, as well as a trickle flow at a selected outlet port and fluid mixing between selected outlet ports.
