The assemblies can by themselves adjust the radial gaps between the assemblies and the liner, and the gaps between the assemblies and the wall of the ring groove in the piston.
The valve is provided with means for displacing the annular piston; at least on the outer and/or inner mantle surface of the annular piston sealing elements are arranged stopping the axial stream of the medium.
The piston sleeve (114) has a pair of piston heads (120, 124), an outer sleeve (114), and an inner sleeve (140).
The sleeve includes a hardened liner and a softer outer jacket The plunger engaging portion of the jacket is of a larger diameter than the plunger engaging portion of the liner to create a gap between the plunger and the soft jacket portion of the sleeve.
The liner has a hardness that is within 10-20 Rc of the hardness of the piston rings carried on a piston within the liner.
Further, the liner defines a piston channel.
A piston is mounted in each liner for reciprocating movement therein.
The sleeve rotates with the objective of improving the lubrication conditions of the piston rings and piston.
The high-pressure assembly (2) comprises a plunger sleeve (20), a plunger (22) to be moved in the plunger sleeve (20) back and forth, and a check valve assembly (24).
A pressurizing chamber (26) is defined between the front end of the plunger (22) and the check valve assembly (24) in the plunger sleeve (20).
For guiding the short piston in the cylinder liner, the arrangement comprises linear bearings acting on the piston rod.
The piston (5) comprises a metallic base part (61) and a jacket (62) made of a plastic material which embodies the running surface of the piston (5).
The sleeve is bonded to an outer surface of the piston, thereby positioning the sleeve between the piston and an inner wall (110) of a piston cylinder (106) .
A retaining nut(48) is secured on the end of the retaining piston (42) and engages one end of the liner (20).
The piston pump (5) has a piston liner (6) with control apertures (17) guided by a tappet (20) fixed to the housing.
