Abstract
The invention refers to a valve, in which a valve housing is deformed and thereby a sliding sleeve pushes against a housing. The invention also refers to a method for manufacturing such a valve.
Claims22
A valve having a longitudinal axis comprising
- a housing,
- a valve housing, and
- a sliding sleeve, which extends along the longitudinal axis,
- wherein the housing has at least one bearing surface, against which the sliding sleeve rests,
- wherein the valve housing at least partially surrounds the sliding sleeve and is connected in a shear-resistant manner to the sliding sleeve at least in the direction of the housing,
- wherein the valve housing has a holding edge which lies radially on the outer side with respect to the longitudinal axis and
- wherein the housing has at least one holding element, which surrounds the holding edge, so that the valve housing is tensioned along the longitudinal axis by elastic deformation of the valve housing towards the housing, wherein the valve housing has a front side facing the housing, which due to elastic deformation, is tilted from an orientation, which is obliquely directed with respect to the longitudinal axis, and wherein the front side is tilted from the orientation, which is oblique with respect to the longitudinal axis, by less than 5°.
4 more elements
A method for manufacturing a valve, wherein the method has the following steps:
- providing a housing, which is at least provided with a bearing surface and a number of holding elements,
- providing a valve housing, which has a holding edge which lies radially on an outer side with respect to a longitudinal axis and wherein the valve housing has a front side facing the housing, which due to elastic deformation, is tilted from an orientation, which is obliquely directed with respect to the longitudinal axis, and wherein the front side is tilted from the orientation, which is oblique with respect to the longitudinal axis, by less than 5°,
- providing a sliding sleeve, which extends along the longitudinal axis,
- arranging the sliding sleeve in such a way that the sliding sleeve rests against the bearing surface of the housing,
- arranging the valve housing in such a way that it at least partially encloses the sliding sleeve and is connected with the sliding sleeve in a shear-resistant manner at least in the direction of the housing, so that the valve housing is blocked on the sliding sleeve, at least against sliding along the longitudinal axis towards the housing, and that the holding edge is positioned radially on the outer side with respect to the longitudinal axis,
- deforming the holding elements, so that they enclose the holding edge, so that the valve housing is tensioned along the longitudinal axis towards the housing by elastically deforming the valve housing.
