Abstract

1513201 Centrifugal governor ROBERT BOSCH GmbH 2 Jan 1976 [28 Feb 1975] 00092/76 Heading G3B [Also in Division F2] A speed regulator incorporated in a rotary compressed air motor with air inlet 39 in a housing 5, has loose balls 32. Acting centrifugally in a chamber 17 connected coaxially with a rotor 4, the chamber having a wall 18 fired axially and a wall 21 axially displaceable against a resilient component 31, one wall having a conical surface 22 facing the balls, the displaceable wall being in one piece with a slide valve on edge 24 of which cooperates with a slot 33 in a cylindrical sleeve extension 19 of the fixed wall 18. As shown a rotor 4 is driven in a stator 3 by air from inlet 39 passing via controlled port 33 into cylindrical space 10 and thereon through ducts 11, 12, 13. As speed increases centrigual force on the balls overcomes the force of the spring, allowing the edge 24 to reduce air-flow through port 33. A seal at the interface 34 is maintained by pressure differential across the member 36 due to air-flow around the spring adjusting nut 29. The balls are contained in a vented chamber which air enters through the clearance 27 between a bolt 25 and displaceable wall 21. Air-flow friction through the clearance inhibits axial oscillation of the displacable wall.
