Feedback spring for the operating means of valves, particularly for manually operable valves

摘要

In valves, particularly in manually operable valves, an elastic restoring element is provided for the automatic feedback of the operating means, which consists of a cellular elastomer as a compression spring (17). The compression spring (17) envelopes the operating means (3) and is supported both on the housing (1) of the valve and on the operating means. The compression spring (17) can consist of a cellular polyurethane. IMAGE
