Abstract

776,279. Centrifugal governors. MARTONAIR N.V., [formerly MATON PERSLUCHT APPARATEN N.V.]. May 14, 1954 [May 15, 1953], No. 14175/54. Class 57. [Also in Group XXIX] A pneumatic time switch comprises an air turbine 2 of regulatable speed driving a rotatable arm 8 through a reduction gear 4 and a clutch 6, 7, the arm operating one or more pneumatic valves 11 during its rotation. The turbine speed is regulated by an adjustable valve 33 controlling a bleed 34 from the turbine inlet and operated through a lever 31, collar 24 and rod 28 by a centrifugal weight 25 mounted on a blade spring 27 carried by the turbine shaft 3. Air pressure at 19 acting on piston 20 and lever 13 engages the clutch. When the arm has operated its valves it opens a further valve to release air at 19, the spring 18 moves the piston and lever to release the clutch and a coil spring 10 or a weighted cord returns the arm to its starting position.
