Radial piston pump for high pressure fuel supply has at least one lubricant pocket in plates

Radial piston pump for high pressure fuel supply has at least one lubricant pocket in plates

The radial piston pump (1) has the slip bearing between a plate (17) connected to the piston foot (15) of a piston (13), and a facet (21) of a polygonal ring (19) to provide lubricant pockets (29). There is at least one lubricant pocket in the plates. The pockets should have a depth from 0.001 to 0....

Zusammenfassung:The radial piston pump (1) has the slip bearing between a plate (17) connected to the piston foot (15) of a piston (13), and a facet (21) of a polygonal ring (19) to provide lubricant pockets (29). There is at least one lubricant pocket in the plates. The pockets should have a depth from 0.001 to 0.1 mm and a diameter between one and two thirds of the diameter of the plates. Es wird eine Radialkolbenpumpe (1) zur Kraftstoffhochdruckerzeugung bei Kraftstoffeinspritzsystemen von Brennkraftmaschinen vorgeschlagen, bei der die Gleitlagerung zwischen einer Platte (17), welche mit dem Kolbenfuß (15) eines Kolbens (13) verbunden ist, und einer Abflachung (21) eines Polygonrings (19) durch Vorsehen von Schmiertaschen (29) verbessert wird.
