Abstract
A cooling channel cover for a piston of an internal combustion engine may include a body having mutually opposite end faces. At least one supply element for a coolant may be received in an opening disposed in the cooling channel cover. The supply element may include an inlet region and an outlet region, and may be held on the cooling channel cover via a clipped-in latching connection. A spring tab may be disposed on the inlet region of the supply element, and/or a latching element may be disposed on the outlet region of the supply element. The spring clip may engage one of the end faces and the latching element may engage the opposite end face.
Claims19
A cooling channel cover for a piston of an internal combustion engine, comprising:
- a body having mutually opposite end faces and an opening;
- at least one supply element for cooling oil having an inlet region and an outlet region, the at least one supply element received in the opening and held on the body via a clipped-in latching connection;
- the at least one supply element including at least one spring tab disposed at the inlet region extending radially outward in a circumferential direction of the body, and at least one latching element disposed at the outlet region that is radially elastic in the circumferential direction of the body;
- wherein the at least one spring tab bears against one end face of the mutually opposite end faces and the at least one latching element bears against the other end face of the mutually opposite end faces;
- and
- wherein the at least one spring tab includes two spring tabs and the at least one latching element includes two latching elements, and wherein the two spring tabs and the two latching elements are disposed radially opposite one another in the circumferential direction of the body.
A piston for an internal combustion engine, comprising:
- a cooling channel cover having a first end face and a second end face disposed mutually opposite one another, and an opening extending transversely therethrough;
- at least one supply element for cooling oil having an inlet region and an outlet region, the at least one supply element received in the opening and held on the cooling channel cover via a clipped-in latching connection;
- the at least one supply element including at least one spring tab disposed at the inlet region extending radially outward in a circumferential direction of the cooling channel cover, and at least one latching element disposed at the outlet region that is radially elastic in the circumferential direction of the cooling channel cover;
- wherein the at least one spring tab bears against the first end face and the at least one latching element bears against the second end face;
- and
- wherein the at least one latching element protrudes radially outwardly from the outlet region of the at least one supply element and extends in a direction towards the inlet region to a free end, and wherein the at least one latching element extends in the direction towards the inlet region with a radial spacing from the at least one supply element.
A cooling channel cover for a piston of an internal combustion engine, comprising:
- a body having mutually opposite end faces and an opening;
- at least one supply element for cooling oil having an inlet region and an outlet region, the at least one supply element received in the opening and held on the body via a clipped-in latching connection;
- the at least one supply element including at least one spring tab disposed at the inlet region extending radially outward in a circumferential direction of the body, and at least one latching element disposed at the outlet region that is radially elastic in the circumferential direction of the body;
- wherein the at least one spring tab bears against one end face of the mutually opposite end faces and the at least one latching element bears against the other end face of the mutually opposite end faces;
- and
- wherein the at least one supply element has a passage opening defining a cross section having a radius that is larger in the circumferential direction of the body than in a radial direction of the body.
