A piston for use in a shock absorber, the piston comprising:
- a first side of the piston and a second side of the piston, wherein the first side of the piston is associated with a first cylinder chamber of the shock absorber, and wherein the second side of the piston is associated with a second cylinder chamber of the shock absorber;
- a first main channel in the piston, and a first main non-return valve in the piston and associated with the first main channel, such that the first main channel and the first main non-return valve allow and damp a first main fluid flow from the second side to the first side of the piston;
- a second main channel in the piston, and a second main non-return valve in the piston and associated with the second main channel, such that the second main channel and the second main non-return valve allow and damp a second main fluid flow from the first cylinder chamber to the second cylinder chamber;
- a comfort channel arranged in the piston to allow an auxiliary fluid flow between the first and second sides of the piston;
- a comfort valve configured and arranged in the piston in the comfort channel such that the comfort valve provides for an open connection for the auxiliary fluid flow through the comfort channel in a rest position of the comfort valve and gradually closes off the auxiliary fluid flow at increasing pressure difference across the comfort valve at either inward or outward movement to influence the auxiliary fluid flow between the first and second sides of the piston,
- wherein the comfort valve comprises a deformable annular plate having at least one flow opening through the annular plate for the auxiliary fluid flow, and wherein the annular plate deforms in response to the increasing pressure difference such that the at least one flow opening deforms against at least one closing surface of the piston to close off the at least one flow opening against the at least one closing surface
- a ring-shaped connecting member;
- a first central member that includes the at least one closing surface and that is received in the connecting member at a first side of the connecting member, which is transverse to a longitudinal direction of the piston and associated with the first side of the piston, wherein a first central member channel is provided on a side of the first central member, which is transverse to the longitudinal direction of the piston and associated with the second side of the piston (11), and wherein the first central member channel is in fluid communication with the second side of the piston;
- and
- a second central member that includes the at least one closing surface and that is received in the connecting member at a second side of the connecting member, which is transverse to the longitudinal direction of the piston and associated with the second side of the piston, wherein a second central member channel being is provided on a side of the second central member, which is transverse to the longitudinal direction of the piston and associated with the first side of the piston, wherein the second central member channel is in fluid communication with the first side of the piston, and
- wherein the comfort channel comprises the first and second central member channels and the comfort valve is provided in between the first and second central member channels.
