    摘要： In a preferred embodiment, a crosshead type piston for an internal combustion engine has a skirt member formed separately from the head member and both are independently connected with the piston pin. The head member carries the compression rings in a ring belt section integrally depending from the crown section, both of which are formed integrally with a piston pin receiving section. The latter section positively connects the head member to the piston pin and includes a saddle portion with a recess in load transmitting relationship with the piston pin so as to transfer downward combustion and inertia loads to a major portion of the piston pin upper surface. Oil distribution means provide for cooling the piston crown and lubricating the pin surfaces, and seal means between the head and skirt prevent excessive leakage of the cooling oil to the cylinder walls. A number of other features are included.
