Radialkolbenpumpe, insbesondere Kraftstoffpumpe für Verbrennungsmotoren

Radial piston fuel pump for combustion engine - uses valve plate contained entirely within recess in cylinder head

Abstract

Radial piston fuel pump for a combustion engine having a valve plate (50) arranged between a cylinder (11) and a cylinder head (51) on which a pair of valve seats (46, 47) is formed. The valve plate is contained entirely within a recess (53) in the cylinder head, and the surfaces of the cylinder and the valve plate in contact with each other are fine-machined to provide a sealing fit. ADVANTAGE - Ensures that in the event of a valve failure the material loss is kept small, since only the valve plate needs to be replaced.
