  • the switching valve or the housing shell connected to the support housing by a so-called clinch.
  • clinch When clinching the light metal of the support housing is plastically deformed and there is a positive connection of the switching valve with the support housing. Since during the clinch process material of the support housing is plastically deformed, the connection can not be detached non-destructively. When a defective switching valve therefore can not replace the defective component, but it must be completely changed the switching valve with the support housing.
  • the object of the invention is therefore to improve the attachment of the switching valve in the support housing so that the disadvantages described above are avoided and a stable permanent attachment is achieved with simple means and cost.
  • the switching valve should be easy and quick to assemble and disassemble without damaging the support housing.
  • the object of the invention is achieved in that the Befest onlyseinrich- device has a retaining clip which produces a positive connection between the housing shell and the support housing.
  • the retaining clip is in operative connection with grooves in the housing shell and in the support housing. In these grooves, the retaining clip is inserted simultaneously during assembly.

  • An anti-rotation of the retaining clip is achieved via key surfaces on the support housing and a locking lug on the retaining clip.
  • the locking nose prevents simultaneous migration of the retaining clip from the grooves in the longitudinal direction.

Abstract

L'invention concerne un dispositif de fixation d'une soupape de commutation (1), comprenant une enveloppe de carter (3), de préférence en acier, dans laquelle sont disposés un corps de soupape (4) contrôlé par une unité électromagnétique (2), un siège de soupape (5) et au moins une ouverture d'amenée et d'évacuation, et comprenant un carter de soutien (8) dans lequel l'enveloppe de carter (3) est fixée de manière étanche. La soupape de commutation (1) fait partie intégrante d'un système hydraulique, de préférence aux fins de la commande des soupapes d'échange des gaz sur des moteurs à combustion interne à pistons alternatifs. Le dispositif de fixation comporte une agrafe de retenue (12) établissant une liaison par complémentarité de forme entre l'enveloppe de carter (3) et le carter de soutien (8).
