GASKET FOR HIGH-PRESSURE PUMP AND HIGH-PRESSURE PUMP COMPRISING SAID GASKET

摘要

A high-pressure pump is provided with a high-pressure delivery line (12), a low- pressure supply line (9), a pumping element (4) defined by a piston (6) and cylinder (5), a cylinder (5) head (8), and a gasket (13), which latter is essentially flat and is provided with a sheet (14) extending in a first plane (P) and having a first hole (17) defining part of the low-pressure supply line (9), a second hole (18) into which the cylinder (5) head (8) can be inserted, and a third hole (19) defining part of the high-pressure delivery line (12); and with a coating (34) of elastic material that extends only around the first and second holes (17, 18).
