Abstract

Abstract A rotary valve including a housing having a chamber within which rotates a sleeve having at least one port for intermittent communication with a discharge port in the chamber, and a second sleeve within the first having a port adapted for communication with the port in the outer sleeve, the second sleeve being adjustable in its rotational position to control cutoff. An adjustable ported sleeve may be provided outside the rotor sleeve for controlling the timing.
