First claim
Opening claim text (preview).
The invention claimed is: 1. A pump for reducing agents of an exhaust gas purification system for an internal combustion engine of a motor vehicle, the pump comprising: a diaphragm carrier; a diaphragm arranged on the diaphragm carrier, the diaphragm having a radially outer collar; and a pump housing configured to secure the radially outer collar of the diaphragm, wherein the radially outer collar of the diaphragm has a reinforcing ring entirely arranged on a radially outermost portion of the radially outer collar. 2. The pump as claimed in claim 1 , further comprising a holding groove defined by housing parts of the pump housing, wherein the radially outer collar of the diaphragm completely fills the holding groove. 3. The pump as claimed in claim 1 , wherein the reinforcing ring is clamped between two housing parts of the pump housing. 4. A pump for reducing agents of an exhaust gas purification system for an internal combustion engine of a motor vehicle, the pump comprising: a diaphragm carrier; a diaphragm arranged on the diaphragm carrier, the diaphragm having a radially outer collar; and a pump housing configured to secure the radially outer collar of the diaphragm, wherein the radially outer collar of the diaphragm has a reinforcing ring, and wherein the reinforcing ring comprises metal. 5. The pump as claimed in claim 1 , wherein the reinforcing ring is connected in an integrally joined manner to elastomeric material of the diaphragm. 6. The pump as claimed in claim 1 , wherein the reinforcing ring is pressed on the pump housing.
