Abstract
A pneumatic piston for an electropneumatic modulator in which the modulator includes a piston housing with a chamber for receiving the pneumatic piston. The pneumatic piston includes a sealing element for sealing an intermediate space between the pneumatic piston and the piston housing; a piston body with a recess for receiving the sealing element; and a securing element configured to fix the sealing element in the recess in a form-fitting manner.
Claims10
A pneumatic piston for an electropneumatic modulator, the electropneumatic modulator having a piston housing with a chamber for receiving the pneumatic piston, comprising:
- a sealing element for sealing an intermediate space between the pneumatic piston and the piston housing;
- a piston body with a recess for receiving the sealing element;
- a securing element configured to fix the sealing element in the recess in a positively locking manner;
- and
- a locking element configured to lock the securing element on the piston body.
An electropneumatic modulator for a brake system of a utility vehicle, comprising:
- a pneumatic piston, wherein the electropneumatic modulator has a piston housing with a chamber for receiving the pneumatic piston, including:
- a sealing element for sealing an intermediate space between the pneumatic piston and the piston housing;
- a piston body with a recess for receiving the sealing element;
- a securing element configured to fix the sealing element in the recess in a positively locking manner;
- and
- a locking element configured to lock the securing element on the piston body.
A method for producing a pneumatic piston, the method comprising:
- forming a piston body with a recess for receiving the sealing element;
- inserting a sealing element into the recess of the piston body, so as to seal an intermediate space between the pneumatic piston and a piston housing;
- and
- locking the sealing element in the recess by a securing element;
- wherein a locking element locks the securing element on the piston body.
