Abstract
A valve for controlling fluid flow through a passage defined by a valve body or a piston includes a valve disc which abuts the valve body or the piston. The valve body or the piston defines a first supporting member for the valve disc, a second supporting member for the valve disc located radially inward from the first supporting member and a third supporting member for the valve disc located between the first and second supporting members. This valve disc abuts the first and second supporting members and a clearance is defined between the valve disc and the third supporting member.
Claims22
A damper comprising:
- a pressure tube forming a working chamber;
- a reservoir tube disposed around said pressure tube, said reservoir tube forming a reservoir chamber between said pressure tube and said reservoir tube;
- a base valve assembly disposed between said working chamber and said reservoir chamber, said base valve assembly comprising:
- a valve body defining a fluid passage, said valve body defining a first supporting member, a second supporting member disposed radially inward from said first supporting member and a third annular supporting member disposed between said first and second supporting members, said third annular supporting member defining an annular support surface;
- a valve disc disposed adjacent said valve body, said valve disc abutting said first and second supporting members, a clearance being formed between said valve disc and said entire annular support surface of said third annular supporting member.
A damper comprising:
- a pressure tube forming a working chamber;
- a piston disposed within said working chamber, said piston dividing said working chamber into an upper working chamber and a lower working chamber, said piston defining a first supporting member, a second supporting member disposed radially inward from said first supporting member and a third annular supporting member disposed between said first and second supporting members, said third annular supporting member defining an annular support surface;
- a valve disc disposed adjacent said piston, said valve disc abutting said first and second supporting members, a clearance being formed between said valve disc and said entire annular support surface of said third annular supporting member.
