  Kolben. 
 EMI1.1 
 verbunden sind. 



   Die Versteifung des Kolbens besteht aus Spreizeu 10 aus einem Werkstoff, der eine geringere Wärmedehnung hat. als der des Kolbens selbst. also z.   H.   Stahl. Die besondere   Gestaltung   dieser Spreizen und ihre Verbindung mit dem Kolbenkörper bildet nun den Er- 
 EMI1.2 
 des Kolbens erzielt. 



   Zu diesem Zwecke sind die Enden jeder Spreize entweder mit einem durchlaufenden 
 EMI1.3 
 fach umschliesst. 



   Eine gute Gussverbindung lässt sich auch dadurch erzielen. dass an den Spreizenenden nur eine einzige   Ausnehmung   angebracht ist, von der aus   ein Schlitz quer durch den ver-   bliebenen Steg hindurchführt (Fig. 3). Die auf solche Weise   entstehenden   T-fijrmigen Köpfe können allseits vom Gussmetall umflossen werden und geben sehr feste Verankerungen. 
 EMI1.4 
 werden die die Stege   bildenden Ausnehmungen   so angebracht, dass sie   näher zu diesem   unteren Längsrande zu liegen   kommen,     als zu dem oberen Hände.

  Piston.
 EMI1.1
 are connected.



   The stiffening of the piston consists of Spreizeu 10 made of a material that has a lower thermal expansion. than that of the piston itself. H. steel. The special design of these spreaders and their connection with the piston body now forms the
 EMI1.2
 of the piston achieved.



   For this purpose, the ends of each spreader are either covered with a continuous
 EMI1.3
 fold encloses.



   A good cast connection can also be achieved in this way. that only a single recess is made at the spreader ends, from which a slot extends transversely through the remaining web (FIG. 3). The T-shaped heads created in this way can be surrounded by cast metal on all sides and provide very firm anchoring.
 EMI1.4
 the recesses forming the webs are attached so that they come to lie closer to this lower longitudinal edge than to the upper hand.

Claims

PATENT CLAIMS: 1. Piston, in which neck parts reaching down from the head carry the journal bearings and whose jacket is stiffened by a pair of spreaders, characterized in that the ends of the spreaders form continuous or interrupted vertical webs (30) which are cast in the guide parts of the jacket . so that the material of these parts surrounds the webs one or more times.

2 piston according to claim 1, characterized in that the continuous or interrupted web at each end of the spreaders is formed by one or more recesses (18 or 33) near the end of the spreaders.

3. Piston according to claim 2, in which only a single Ausnelminng is provided at the spreading ends. characterized in that of this a slot (Fig. 3) is passed transversely through the vertical web formed by the recess, so that a EMI2.1 Spread are bent out of the plane of the spreaders.

5. Piston according to claim 2, in which a semicircular cutout is provided in the lower longitudinal edge of each spreader, characterized in that the recess (18) or the recesses (33) are arranged at the spreader ends. that they are closer to the lower longitudinal edge than to the upper one. EMI2.2
