Abstract
Telescoping vibration damper consisting of a work cylinder and a jacket tube forming an equalization chamber, whereby there is a base valve in the floor of the work cylinder. The object is to create a simple base valve which can be simply and economically manufactured and which allows an optimum flexibility of design, whereby the correct formation of the control edges can be easily accomplished. To achieve this object, the base valve is realized in the form of at least two disks with corresponding notches, whereby the notches of both disks jointly form the flow connection of the base valve and are connected with corresponding valve disks to form a single component.
Claims14
A vibration damper for damping vibrations of a motor vehicle, said vibration damper comprising:
- a first tubular member;
- means for attaching said vibration damper to one of:
- a wheel suspension and a support structure of the motor vehicle;
- said first tubular member defining a chamber therewithin, said chamber comprising damping fluid therewithin, and said first tubular member defining a longitudinal dimension;
- piston rod means, said piston rod means having a first end within said first tubular member and a second end external to said first tubular member, said piston rod means being movable within said first tubular member in a direction along said longitudinal dimension of said first tubular member;
- means for attaching said second end of said piston rod means to the other of:
- the wheel suspension and the support structure of the motor vehicle;
- piston means disposed at said first end of said piston rod means, said piston means having a first side disposed adjacent said piston rod means and a second side opposite to said first side, and said piston means dividing said chamber into a first work chamber adjacent the first side thereof and a second work chamber adjacent the second side thereof;
- a base;
- said base being disposed at said second work chamber;
- a passage for leading damping fluid from said second work chamber;
- a base valve disposed in said base
- said base valve comprising a flow connection of damping fluid between said second work chamber and said passage to permit flow from said second work chamber to said passage;
- said base valve comprising at least a first disk and a second disk;
- said first disk and said second disk comprising apertures;
- said apertures comprising means for mounting said first disk and said second disk non-rotationally with respect to one another to form said flow connection;
- said aperture of said first and second disks comprising at least a part of said flow connection between said second work chamber and said passage;
- said apertures of said first and second disks comprising at least a first flow connection and a second flow connection;
- said first flow connection comprising a first check valve for permitting flow in a direction from said second work chamber to said passage;
- said second flow connection comprising a second check valve for permitting flow in a direction from said passage to said second work chamber;
- said first check valve comprising at least one valve disk;
- said second check valve comprising at least one valve disk;
- said base valve having a first side and a second side;
- said first valve disk being disposed on said first side of said base valve;
- and
- said second valve disk being disposed on said second side of said base valve.
