A SPRING AND A VALVE INCORPORATING SUCH A SPRING

摘要

The invention provides an assembly spring (1) and a valve incorporating such a spring. The spring is made from a wire which extends around a longitudinal axis to form windings (4, 5). The spring terminates in axially opposite end portions in first and second end windings. The énd windings each has an arcuate portion wherein the wire extends around the longitudinal axis. The end windings serve to fasten the spring in a groove of an element to which the spring is being attached. The end winding further has a free end portion (6) wherein a free wire end extends outwardly away from the longitudinal axis to form gripping means. The spring thereby facilitates easy attaching of the end winding to the element. In particular, the spring is applicable for attaching a valve element to a plunger in a valve, e.g. a servo valve.
