Claims18
A device for controlling movement of a valve within a body comprising:
- (a) first and second chambers having a fluid;
- (b) passage means communicating with said first and second chambers for displacement of said fluid between said chambers through said passageway upon movement of said valve;
- (c) a spool adapted for slideable movement within said body wherein one end of said spool is adapted to receive a stationary plunger;
- (d) said spool includes an undercut presenting first and second orifice means communicating with said first and second chambers respectively.
An adjustable control apparatus for a hydraulic shifter having a body comprising:
- (a) a valve means moving between a first and second position within said body and defining a first and second chamber containing a fluid;
- (b) an adjustable means presented by said body and co-operating with said valve means so as to control the rate of communication of said fluid between said first and second chambers as said valve means moves between said first and second position.
A method of using an adjustable control apparatus for a hydraulic shifter comprising:
- (a) moving a valve means between a first and second position within a body, said valve means and body defining a first and second chamber containing a fluid;
- (b) adjusting the rate of movement of said valve between said first and second position by adjustable means secured to said body for controlling the rate of communication of said fluid between said first and second chambers as said valve means moves between said first and second position.
A method of using an adjustable control apparatus for a hydraulic shifter having first and second chambers containing a liquid comprising:
- (a) moving a valve means having a lever, a spool and at least one passage between a first and second position, said valve means moveable within a body and defining a first and second chamber containing a fluid;
- (b) adjustable means secured to said body for controlling the rate of communication of said liquid between said first and second chambers as said valve means moves between said first and second position by engaging said lever and said spool.
A device for controlling the movement of a valve moving between a first and second position within a body;
- said valve and body defining a first and second chamber containing a fluid;
- a plunger secured to said body;
- one end of said valve receives said plunger as said valve moves within said first and second position;
- said one end of said valve including passage means communicating with said first and second chambers;
- said plunger includes an adjustable needle for opening and closing said passage means so as to control the rate of communication of said fluid between said first and second chamber as said valve moves between said first and second position.
