Abstract
Official abstract text for this publication.
A guide ring for a pump element of a hydraulic unit of a vehicle brake system is configured to guide a pump piston in a pump housing when the pump piston is displaced along the axis thereof in the pump housing. On the inner side of the guide ring facing the pump piston, the guide ring includes a first step that has a first inner diameter and a second inner diameter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A guide ring for a pump element of a hydraulic unit of a vehicle brake system, the guide ring configured to guide a pump piston in a pump housing when the pump piston is displaced along its axis in the pump housing, the guide ring comprising: a first step having a first inside diameter and a second inside diameter on its inner side facing the pump piston, wherein the guide ring is configured with a tapered portion on an outer side of the guide ring, and wherein the second inside diameter is between the first inside diameter and the tapered portion. 2. The guide ring as claimed in claim 1 , wherein the guide ring is configured with a second step having a third inside diameter on its inner side facing the pump piston. 3. The guide ring as claimed in claim 1 , wherein the guide ring is configured with a third step having a first outside diameter and a second outside diameter on its outer side facing the pump housing. 4. The guide ring as claimed in claim 1 , wherein the tapered portion faces the pump housing and is tapered away from the first step. 5. A kit for a hydraulic unit module for a vehicle brake systems, the hydraulic unit module including a pump housing and at least two pump pistons, the pump housing having an internal contour and the at least two pump pistons each having different outside diameters, the kit comprising: a first guide ring and a second guide ring, the first guide ring including a first step having a first inside diameter and a second inside diameter on its inner side facing the pump pistons, the second guide ring including a second step having a third inside diameter and a fourth inside diameter on its inner side facing the pump pistons, wherein the first guide ring and the second guide ring are configured for arrangement on (i) the internal contour of the pump housing and (ii) the different outside diameters of the at least two pump pistons.
