466,572. Valves. ECLIPSE AVIATION CORPORATION. Nov. 29, 1935, No. 33148. Convention date, Nov. 30, 1934. [Class 135] A rotary distributing valve comprises a housing 11 with a series of outlet ports 16 which are placed in communication periodically, through a port 17 in a rotary valve member 12, with a fluid pressure supply 19 to the housing and, through a port 18, with an exhaust opening 21. The valve rotor 12 is slidably but non- rotatably mounted on a driving shaft 22 by means of a pin-and-slot arrangement 42, 43 and is adjusted axially on the shaft by a screw stop 44 against which it is thrust by a spring 4(i, the shaft itself being positioned by a thrust bearing 23. The shaft 22 and therefore the valve rotor 12 is driven by an electric motor 37 through reduction gearing 36, 34, 31, 28, combined in a single unit with the valve casing. A particular application of the invention is to de-icer systems for aircraft.
