ABSTRACT:
The piston head is hollowed for a central coolant cavity and for an outer annular coolant cavity separated by a ridge by which the head is supported on the piston body. An outer shoulder also supports the skirt part of the head on the piston body. The piston body has an upper part hollowed in the center to form part of the central coolant cavity and a lower part having a wrist pin bearing with coolant recesses in the bearing, which are connected by coolant channels leading to the annular cavity in the head. The wrist pin in the bearing has channels connecting a coolant supply channel in the piston rod to the center of the wrist pin and thence to the bearing recesses.
