Abstract
The valve actuator comprises a base part 1 with a base flange 3 and an output shaft 5 mounted in the latter, as well as a cylinder 6 containing a piston 7 with a tubular conversion member 8 designed integrally therewith with external and internal grooves 9 and 11 which, by engaging with corresponding grooves 10 and 12 in a central bore in the base part 1 and on the output shaft 5, convert an upward or downward movement of the piston 7 to a rotational movement of the piston 7 and the output shaft 5 in one direction or the other, and a spring housing 2 consisting of a shell 16 and a cover 17 and containing a cup-spring stack 13, the latter acting with a downwardly directed force on the piston 7 via a spring hub 26 and a thrust roller bearing 28. When pressurized fluid is supplied to the space below the piston 7 and the conversion member 8, these components move upwardly against the force from the cup-spring stack 13, causing the output shaft 5 to rotate in one direction, while, when the fluid pressure is released, the force from the cup-spring stack 13 moves the piston 7 and the conversion member 8 downwardly, and the output shaft 5 rotates in the opposite direction. <IMAGE>
