A high pressure pump has a housing with a crank shaft 10 which drives a plurality of pistons 14 in each case via a connecting rod 12, with each piston being guided in a cylinder 16 which is secured to a cylinder head 18 and which sucks fluid from an inlet and delivers it under pressure to an outlet, where a sliding shoe 34 is provided as a connection rod guide that the piston is insertable in a form-fitted manner. Preferably the housing has ribs to take up the forces between the crank shaft and the cylinder head. An oil sump may be provided in the housing such that part of the fluid is directed through cooling pipes that are guided through the oil sump. There may also be two sliding ring seals to seal the piston in the cylinder, between which there is a monitoring passage for the oil pressure. |
