Definitions

  • the present invention relates to a precompressed elastic element particularly for fluid-operated actuators.
  • fluid-operated actuators used for example for the remote actuation of valves and the like currently use precompressed elastic elements designed to perform the return stroke of pistons provided with a rack or slot link which interact with the actuation pin of the valve element.
  • Such precompressed elastic elements are provided in the most disparate manners and generally speaking consist of a male element and a female element, which retain a spring between them and can slide with respect to each other so as to cause the compression that makes it possible to perform the return stroke.
  • the precompressed elastic element consists of a male element and a female element, which can slide with respect to each other and are provided with flanges on which the female element operates.
  • the female element has a bush-like body, in which a stem of the male element can slide which has a protruding abutment rim that engages an annular rim of the bush for providing the extraction-preventing means.
  • screw means are provided which make it possible to connect the stem of the male element, inserted in the bush-like body of the female element, to the flanged element, thus making the precompression of the spring stable.
  • This type of solution entails first of all the need to have several components in order to provide the male element, and the assembly step is complicated, since screwing must be provided during the step for compression of the spring.
  • the aim of the invention is to eliminate the drawbacks noted above, by providing a precompressed elastic element particularly for fluid-operated actuators that allows monolithic provision of the male element, with the advantage of obtaining a precompression coupling of the spring that is particularly quick and easy.
  • an object of the invention is to provide an elastic element that can be assembled without using screw means, further having extraction-preventing means which are particularly safe, since an action is provided which enhances clamping during extrusion of the spring.
  • a precompressed elastic element particularly for fluid-operated actuators comprising a male element and a female element which can slide with respect to each other, a spring being further provided which operates between a first flange, which is associated with said male element, and a second flange, which is associated with said female element, characterized in that it comprises means for snap coupling between said male element and said female element which form extraction-preventing means.
  • Figure 1 is a schematic exploded view of a precompressed elastic element
  • Figure 2 is a view of the precompressed elastic element in the assembled condition
  • Figure 3 is an axial sectional view of the precompressed elastic element
  • Figure 4 is a schematic view of the elastic element fitted in a fluid- operated actuator.
  • the precompressed elastic element particularly for fluid-operated actuators comprises a male element 2 and a female element 3, which can slide with respect to each other.
  • the male element 2 has a stem 4 which has, at one end, a first flange 5.
  • the stem 4 can slide with respect to a bush-like body 6 of the female element 3, which has a second flange 7.
  • a spring 8 operates on a first flange 5 formed by the male element 2 and a second flange 7 formed by said female element. When the male and female elements are mutually joined, the spring is advantageously precompressed.
  • snap coupling means are provided which, in a preferred embodiment, consist of tabs 10, which can flex elastically in a radial direction and are formed at the end of the stem 2.
  • Teeth 11 are provided at the free end of the tabs 11 and have a tapering portion 12 for insertion and an engagement tooth 13 which forms, together with the stem 4, an engagement seat 14 that is frustum-shaped, with an acute apex angle.
  • the bush-like body 6 forms an annular rim 20, which provides a complementary mating tooth 21 , which can be inserted in the annular seat 14 and has at its vertex an angle of less than 90°, so as to perform an insertion in the seat which, once assembly has been performed, makes mutual disengagement between the male element and the female element impossible.
  • the extraction-preventing means provided by the coupling between the annular seat and the annular abutment tooth are particularly stable, and therefore the reliability of the precompressed elastic element is always ensured.
  • the materials used may be any according to requirements.

Abstract

La présente invention concerne un élément élastique pré-comprimé (1), qui est destiné en particulier à des actionneurs commandés par fluide, et qui comprend un élément mâle (2) et un élément femelle (3) pouvant coulisser l'un par rapport à l'autre. L'élément mâle (2) présente une formation constituant une première bride (5), l'élément femelle (3) présente également une formation constituant une seconde bride (7). Enfin, des organes (10) permettant l'emboîtement en force entre l'élément mâle (2) et l'élément femelle (3), constituent autant de moyens interdisant leur séparation.
