Abstract

1470818 Fluid-pressure servomotor systems BERINGER-HYDRAULIK GmbH 25 June 1974 [26 June 1973] 28054/74 Heading G3P In a servo-control valve, a main spool 4 is fluid actuated by a pilot spool 22 with which it has a feedback connection through a spring 25, the pilot spool being operated by electromagnets 19, 20. The main spool controls communication between service ports 5, 6, exhaust ports 8 and an inlet port 7 which also supplies the pilot spool through a passage 13. The spring is of circular cross-section with a ball-shaped end engaged in a transverse bore of the pilot spool. To maintain uniform bonding stress, the surface of the spring is shaped as a cubic parabola.
