A high-pressure pump is provided with a high-pressure delivery line, a low-pressure supply line, a pumping element defined by a piston and cylinder, a cylinder head, and a gasket. The gasket is essentially flat and is provided with a sheet extending in a first plane and that has a first hole defining part of the low-pressure supply line, a second hole into which the cylinder head can be inserted, and a third hole defining part of the high-pressure delivery line. A coating of elastic material is provided to extend only around the first and second holes.

Gasket for high-pressure pump and high-pressure pump comprising said gasket

A high-pressure pump for supplying fuel to an internal-combustion engine has a pump body and an actuating shaft which extends along a longitudinal axis and which is supported rotatably about the longitudinal axis by the pump body. The shaft has an eccentric portion and a prismatic jacking end. A first pumping station has a gear engaged with the prismatic jacking end and a second pumping station has at least one piston. The piston is slidable relative to the pump body transversely with respect to the longitudinal axis and is actuated by the eccentric portion of the actuating shaft. The prismatic jacking end is made of a harder material than the material with which the remainder of the actuating shaft is made.
