Abstract
A piston has a pair of support members extending away from the piston head offset from a piston ring portion, a piston rod being carried on a connecting rod which is clamped between the support members by a bolt. The bolt is loosely received in a bore in the connecting rod, the force between the piston and the piston rod being taken by a frictional force between the connecting rod and the support members to prevent a bending force being applied to the bolt.
Claims4
A piston and piston rod arrangement for a reciprocating piston engine, said arrangement comprising:
- a. a piston having a piston head, a piston ring portion and a pair of support members integral with said piston head and extending away from said piston head in spaced relationship with respect to the piston ring portion;
- b. a connecting rod positioned between and in contact with said support members, said connecting rod being so shaped as to define a bore therethrough;
- c. a piston rod carried on said connecting rod;
- d. a bolt passing through said support members and through said bore to exert a clamping force between said support members and said connecting rod, the bolt having an intermediate portion which passes through said bore and which has a diameter less than that of said bore;
- and
- e. cooperating shoulders formed on said connecting rod and said support members to prevent movement of said connecting rod in a direction towards said piston head.
