Claim 1
Independent Claim
218 words
A shock absorber with a variable damping characteristic, particularly for use in vehicles, comprising at least one hollow cylinder defining an internal space for confinement of a damping fluid and having a first and a second end; a piston-piston rod assembly including a piston rod sealingly extending through one of said ends and into said cylinder, and a piston disposed in and being in sealing engagement with said cylinder so as to divide said internal space into first and second chambers, said assembly having at least one passage for the flow of damping fluid between said chambers and said assembly further having a plurality of bypasses extending between said chambers; and means for regulating the flow of damping fluid through said bypasses, including a valving element for each bypass and an exciter coil for each valving element, said valving elements being concentric with each other and each valving element being mounted in said assembly for sliding movement with reference to said assembly and relative to the respective bypass, said assembly and said valving elements having closely adjacent confronting surfaces and said assembly further having hydrostatic bearing means including means for continuously supplying a lubricant between said valving elements and said assembly, said lubricant supplying means including at least one annular groove provided in one of said confronting surfaces.

A shock absorber with a variable damping characteristic, particularly for use in vehicles, comprising at least one hollow cylinder defining an internal space for confinement of a damping fluid and having a first and a second end; a piston-piston rod assembly including a piston rod sealingly extending through one of said ends and into said cylinder, and a piston disposed in and being in sealing engagement with said cylinder so as to divide said internal space into first and second chambers, said assembly having at least one passage for the flow of damping fluid between said chambers and said assembly further having a plurality of bypasses extending between said chambers; and means for regulating the flow of damping fluid through said bypasses, including a valving element for each bypass and an exciter coil for each valving element, said valving elements being concentric with each other and each valving element being mounted in said assembly for sliding movement with reference to said assembly and relative to the respective bypass, said assembly and said valving elements having closely adjacent confronting surfaces and said assembly further having hydrostatic bearing means including means for continuously supplying a lubricant between said valving elements and said assembly, said lubricant supplying means including at least one annular groove provided in one of said confronting surfaces.
Claim 3
Dependent Claim
13 words
The shock absorber of claim 1, wherein the lubricant is said damping fluid.
Claim 4
Dependent Claim
39 words
The shock absorber of claim 1, wherein said regulating means is electrically operated and said assembly includes seat means for said valving elements, said supplying means being arranged to supply lubricant between said valving elements and said seat means.
Claim 5
Dependent Claim
23 words
The shock absorber of claim 3, wherein said seat means includes a single seat which is common to all of said valving elements.
Claim 6
Dependent Claim
13 words
The shock absorber of claim 4, wherein said single seat includes a cylinder.
Claim 7
Dependent Claim
16 words
The shock absorber of claim 1, wherein each exciter coil concentrically surrounds the respective valving element.
Claim 8
Dependent Claim
22 words
The shock absorber of claim 1, wherein said coils are concentric with each other, with said valving elements and with said assembly.
Claim 9
Dependent Claim
26 words
The shock absorber of claim 1, wherein said valving elements include an inner valving element and an outer valving element which surrounds said inner valving element.
Claim 10
Dependent Claim
24 words
The shock absorber of claim 8, wherein said at least one passage is provided in said assembly radially outwardly of said outer valving element.
