Abstract

A supporting arrangement for an eccentric member (8) of an adjusting arrangement (6) of a connecting rod (2) of a reciprocating piston internal combustion engine having at least one piston rod (18) that is guided displaceably by a piston (20) and a seal member (24) is connected to the supporting piston (20) in a supporting cylinder (12, 14) which is provided in the connecting rod (2) and has a longitudinal axis (16). The supporting piston (20) enclosing at least one cylinder chamber (22) with the supporting cylinder (12, 14). A side (28) of the supporting piston (20) that is directed toward the cylinder chamber (22) has a brake piston (30) that can be moved in the longitudinal axis (16). The brake piston (30) is mounted on the supporting piston (20) and can be prestressed by a spring (32).

First claim

What is claimed is:

1. A supporting arrangement for an eccentric member of an adjusting arrangement of a connecting rod of a reciprocating piston internal combustion engine having at least one piston rod guided displaceably by a piston and a seal that is connected to the supporting piston in a supporting cylinder that is provided in the connecting rod and has a longitudinal axis, the supporting piston enclosing at least one cylinder chamber with the supporting cylinder wherein the supporting piston has a brake piston on a side directed toward the cylinder chamber, the brake piston is mounted on the supporting piston and can be moved in the longitudinal axis; and a prestressing means for prestressing the brake piston.

2. The supporting arrangement of claim 1 , wherein the prestressing means has at least one spring member.

3. The supporting arrangement of claim 2 , wherein the prestressing means is configured as a leaf spring arrangement that is supported on a wall.

4. The supporting arrangement of claim 1 , wherein the brake piston has an opening arrangement configured as a nozzle.

5. The supporting arrangement of claim 4 , wherein the opening arrangement is configured as a throttle opening.

6. The supporting arrangement of claim 4 , wherein the opening arrangement is configured as an annular gap.

7. An adjusting arrangement having the supporting arrangement of claim 1 , wherein the supporting arrangement has two supporting cylinders each of which has one piston rod and one supporting piston.
