Abstract
A position sensitive apparatus is disclosed herein. The apparatus includes a position sensitive base valve comprising a plurality of ports and check plate to reduce fluid flow through at least one of the plurality of ports of the position sensitive base valve based on a location of a damping piston. The apparatus also includes a first spring coupling the check plate with the position sensitive base valve, the first spring biases the check plate away from the position sensitive base valve.
Claims23
A position sensitive apparatus comprising:
- a position sensitive base valve comprising a plurality of ports;
- a check plate, configured to reduce a flow rate through at least one port of said plurality of ports of said position sensitive base valve based on a location of a damping piston;
- and
- a first spring configured to bias said check plate away from said position sensitive base valve.
A position sensitive bottom out zone structure comprising:
- an upper port through a wall of a main chamber to provide a first fluid pathway from said main chamber to a reservoir, said upper port located in a bottom out zone of said main chamber, said upper port comprising a first base valve with a firm compression setting;
- a lower port through said wall of said main chamber to provide a second fluid pathway from said main chamber to said reservoir, said lower port located between said upper port and a damping piston, said lower port comprising a second base valve with a softer compression setting than said first base valve;
- a check plate, configured to reduce a fluid flow rate through said lower port based on a location of said damping piston;
- and
- a spring configured to bias said check plate away from said lower port.
A shock assembly comprising:
- a damper chamber comprising at least one bypass port through a ride zone portion thereof;
- a piston coupled to a piston shaft and configured for operation within said damper chamber, said piston configured to divide said damper chamber into a compression side and a rebound side, wherein said piston will restrict fluid flow through said at least one bypass port when said piston enters a bottom out zone portion of said damper chamber;
- a base valve at a compression end of said damper chamber, said base valve comprising a plurality of ports;
- a check plate configured to restrict fluid flow through at least one of said plurality of ports of said base valve based on a location of a damping piston;
- a first spring coupling said check plate with said base valve, said first spring biases said check plate away from said base valve;
- a second spring coupling said check plate with said damping piston, said second spring biases said check plate away from said damping piston;
- and
- a body cap comprising:
- a bypass channel fluidly coupling said at least one bypass port with a fluid reservoir;
- and
- an adjuster configured to adjust a flow area of said bypass channel.
A position sensitive apparatus comprising:
- a position sensitive base valve comprising:
- at least one valve controlled fluid flow path configured to manage fluid flow therethrough;
- and
- a central bypass flow path configured to provide a bypass of said at least one valve controlled fluid flow path, wherein said fluid flow through said central bypass flow path is unencumbered by said position sensitive base valve;
- a flow limiting check plate, configured to reduce a flow rate through said central bypass flow path based on a location of a damping piston;
- and
- a first spring coupling said flow limiting check plate with said position sensitive base valve, said first spring biases said flow limiting feature of said flow limiting check plate away from said central bypass flow path of said position sensitive base valve.
A position sensitive apparatus comprising:
- a position sensitive base valve comprising at least one base port;
- a check plate comprising a least one check plate port;
- a shim stack coupled with said check plate and located between said check plate and said position sensitive base valve, said shim stack configured to reduce a flow rate through said at least one base port of said position sensitive base valve based on a location of a damping piston;
- and
- a first spring coupling said check plate with said position sensitive base valve, said first spring biases said check plate away from said position sensitive base valve.
