Abstract
A fluid controller (11) of the type comprising a rotatable spool valve (31) and a relatively rotatable follow-up sleeve valve (33), in which fluid flows through a fluid meter (15) of the type in which a star member (39) orbits and rotates as fluid flows through the meter (15). The rotation of the star (39) is transmitted to the sleeve valve (33) to provide follow-up movement thereto. In accordance with the present invention, the star (39) defines a set of internal teeth (41) and a terminal portion (42) of the sleeve valve (33) extends axially into the star and defines a set of external teeth (43), in driven engagement with the internal teeth (41). As a result of the follow-up arrangement of the invention, the need for the conventional drive shaft and transverse pin is eliminated, the spool and sleeve can have smaller diameters, and the overall fluid controller can be smaller, less complicated, and less expensive.
