Abstract
A reciprocating-piston pump with plain bearing traversed by flow. The reciprocating-piston pump is driven by an electromagnet to have a bearing of the piston in a cylinder, which bearing is protected against local overheating and from which bearing decomposition and reaction products and any wear products generated are discharged. For this purpose, elongate helical depressions are provided in one of two bearing surfaces in a bearing gap between the piston and the cylinder, which depressions are traversed entirely or partially by a flow of the liquid which is delivered by the piston acting in interaction with other components of the reciprocating-piston pump for the delivery rate of the reciprocating-piston pump. Reciprocating-piston pumps of the described type can be used as dosing pumps and as delivery pumps in fuel-operated standstill heaters, auxiliary heaters and exhaust-gas purification systems in vehicles.
