Abstract
The invention relates to a one-piece plastic element having an inlet valve cover and an inlet valve seat element for an inlet valve of a piston pump of a hydraulic brake system of a motor vehicle. The inlet valve is designed as a check valve, and the inlet valve cover and the inlet valve seat element are connected to each other by a designed fracture point. The invention further relates to a piston pump having an inlet valve cover and inlet valve seat element made of a one-piece plastic element. The invention further relates to a method for assembling the inlet valve designed as a check valve.
Claims24
A one-piece plastic element, including an inlet valve cap and an inlet valve element for an inlet valve embodied as a check valve of a hydraulic brake system of a motor vehicle, wherein the inlet valve cap and the inlet valve element are aligned along a common axis and are connected to one another via an integral rated breaking point configured so that the inlet valve cap is offset from the inlet valve element along the common axis.
A one-piece plastic element, including an inlet valve cap and an inlet valve element for an inlet valve embodied as a check valve of a hydraulic brake system of a motor vehicle, wherein:
- the inlet valve cap and the inlet valve element are joined to one another via an integral rated breaking point;
- and
- the inlet valve cap has at least two circumferential wall portions, of which at least one is bendable radially outward in order to embody a sufficiently large assembly cross section for the axial insertion of a closing body and of a closing spring element into the inlet valve cap when it is joined to the inlet valve element.
