Abstract
A connection between a first member (e.g. a piston rod) and a bore in a second member (e.g. a piston) which is formed by two spaced grooves on the first member at least one of which is in register with one of two spaced steps in the bore, and a compression clip mounted in each groove such that when the groove and the step are in register the compression clip is in compression between one face of each groove and one face of the corresponding step and the angle between the compression forces acting on the clip and the longitudinal axis of the bore is in the range 30.degree.-70.degree..
Claims23
In a connection between a first member and a bore in a second member, wherein the periphery of the first member has a shape similar to that of the bore and the first member is dimensioned to have a sliding fit within the bore, the improvement comprising:
- two spaced grooves formed around the periphery of the first member, each groove being defined by at least one face;
- two spaced steps formed in said bore, each step being defined by at least one face and being provided by a region of enlarging diameter relative to said bore, said enlarging diameter region extending to the adjacent end of said second member;
- and
- a compression clip located in and occupying a major portion of the circumferential length of each groove, said compression clip having a solid cross-section;
- each step being located and having a configuration so that at least one groove is in register with one of said steps, said compression clip in said at least one groove is compressed between said at least one face of said at least one groove and said at least one face of said one step and the angle between the compressive forces acting upon said compressed clip and the longitudinal axis of the bore is in the range of 30.degree.-70.degree., and the other of said steps is positioned relative to said other groove for providing a predetermined amount of binary cushioning in the range from zero to any positive dimension, between the first member and the second member.
In a connection between a first member and a bore in a second member, wherein the periphery of the first member has a shape similar to that of the bore and the first member is dimensioned to be a sliding fit within the bore, the improvement comprising:
- two spaced grooves formed around the periphery of the first member, each groove being defined by at least one face;
- two spaced steps formed in said second member, each step being defined by at least one face and being provided by a region of enlarged diameter relative to and joined with said bore said enlarging diameter region extending to the respective end of said second member;
- and
- a compression clip having a solid cross-section located in and occupying a major portion of the circumferential length of each groove;
- each groove being in register with a corresponding one of said steps so that each compression clip is compressed between said at least one face of each groove and said at least one face of the corresponding step, and the angle between the compressive forces acting upon each compression clip and the longitudinal axis of the bore is in the range of 30.degree.-70.degree..
