Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A hydraulic timing adjustment arrangement linking a primary and a secondary part of a transmission for driving a fuel injector system for a motor vehicle internal combustion engine, said arrangement comprising: a flexible connector means having one section fixed to move with the primary part and another section fixed to move with the secondary part movable means on the secondary part adjacent to said connector means for deforming said flexible connector means radially to effect a circumferential rotation of the secondary part with respect to the primary part.
Claim 2
Dependent Claim
88 words
A hydraulic timing adjustment arrangement linking a primary and a secondary part of a transmission for driving a fuel injector system for a motor vehicle internal combustion engine, said arrangement comprising: a flexible connector means having one section fixed to move with the primary part and another section fixed to move with the secondary part movable means on the secondary part adjacent to said connector means for deforming said flexible connector means radially to effect a circumferential rotation of the secondary part with respect to the primary part.
Claim 3
Dependent Claim
20 words

Claim 4
Dependent Claim
25 words
A hydraulic timing adjustment arrangement according to claim 2, wherein the radial piston is guided in a cylinder of the secondary part and is crowned.
Claim 5
Dependent Claim
28 words
A hydraulic timing adjustment arrangement according to claim 2, including a bearing sleeve that is rotationally disposed on the injection pump shaft and is unitary with said cylinder.
Claim 6
Dependent Claim
28 words
A hydraulic timing adjustment arrangement according to claim 4, wherein the primary part is rotatably disposed on a part of the bearing sleeve that projects from the end.
Claim 7
Dependent Claim
17 words
A hydraulic timing adjustment arrangement according to claim 1, wherein the primary part has a drive toothing.
Claim 8
Dependent Claim
20 words
A hydraulic timing adjustment arrangement according to claim 1, wherein said flexible connector means is comprised of a multi-link chain.
Claim 9
Dependent Claim
88 words
A hydraulic timing adjustment arrangement according to claim 2, wherein the flexible connector means includes a chain link and a driving arm, said movable means includes a lever means connected to said radial piston and said secondary part adjacent to said connector means such that in the case of a maximum admission of pressure to the radial piston, the chain link , completely rests on the arched back of the lever means, while the driving arm projects beyond the lever means and is fixed at the primary part.
Claim 10
Dependent Claim
31 words
A hydraulic timing adjustment arrangement according to claim 1, including a spring means connected to the primary part and the secondary part, for acting against the force of said movable means.
Claim 11
Dependent Claim
40 words
A hydraulic timing device according to claim 9, wherein said spring means includes a torsion spring connected between said primary and secondary part for biasing said primary and secondary parts circumferentially to an initial angular position relative to each other.
Claim 12
Dependent Claim
43 words
A hydraulic timing adjustment arrangement according to claim 2, wherein the bearing sleeve of the secondary part has an oil bore which connects a pressure space, defined by the walls of the cylinder, with an arrangement of bores in the injection pump shaft.
Claim 13
Dependent Claim
22 words
A hydraulic adjustment arrangement according to claim 2, having three radial pistons positioned equal distances from each other in a circumferential direction.
