Embodiment Construction

[0017] In the following description of the drawings, concepts such as up, down, left, right, front, back, etc. are only for the selected exemplary illustrations and positions of devices and other elements in the drawings. These concepts are to be understood as non-limiting, ie these relationships may vary due to different positions and / or mirror-symmetrical arrangements, etc.

[0018] figure 1 A piston 1 is shown, which consists of a piston skirt 2 and a piston crown 3 . Piston 1 has a sliding shoe 4 . The sliding shoe 4 is prestressed by means of an energy store 5 which is designed in particular as a compression spring and also in particular as a helical spring. This is done for the connecting rod head 8 in the piston-connecting rod system. Between the energy store 5 and the sliding shoe 4 , it is possible, but not necessary, to arrange a spacer 6 which transmits the force from the energy store 5 to the sliding shoe 4 . In order to protect the sliding shoe 4 against comin...

Abstract

The invention relates to a piston (1) of an internal combustion engine having a sliding shoe (4) mounted in an accumulator (5) and having a cavity for receiving cooling oil into a cavity Channel (10) in (11), characterized in that the accumulator (5) is arranged in a channel (12) formed in particular by the piston (1) and the shoe (4) is partly in the accumulator ( 5) Internal guidance.

Description

technical field [0001] The invention relates to a piston of an internal combustion engine having a sliding shoe which is mounted in an energy store and which has a channel for receiving cooling oil into a cavity. Background technique [0002] DE 100 22 035 A1 discloses an internal combustion engine with a combined (gebaut) piston consisting of a steel piston crown and a piston skirt, which are arranged on the central axis or in the center of the piston via a single The screws near the axis are connected to each other; and have a central cooling chamber between the piston crown and the piston skirt; and have a connecting rod for guiding oil, which is connected to the piston skirt by a piston pin. [0003] There is only a small distance between the piston and the connecting rod. With today's shoe geometry solutions of this kind, it is not possible to guide the shoe in the piston. The task of the shoe consists of directing the cooling oil that rises through the connecting rod...
