Power transmitting mechanism for reciprocating engines or pumps

A reciprocating-piston engine or pump having a main shaft and a plurality of cylinders arranged circumferentially around the main shaft of the motor or pump, the axes of said cylinders being parallel to the main shaft, each piston being connected to a crosshead through a piston rod, a swash-plate fixed to the main shaft and gripped by the crosshead while the swash-plate side surfaces are abutted by a main thrust bearing and a rear thrust bearing, slide bearings for absorbing the force components perpendicular to the main shaft, said slide bearings absorbing the inward directed components of the rotating transverse force vector, said slide bearings comprising at least one michell thrust blocks sliding on an outwardly facing rotating cylindrical surface coaxial with said main shaft and rigidly connected to said swash-plate, said cylindrical surface being arranged on a thickening portion of said main shaft and locally cutting into one of the swash-plate side surfaces so as to form a recess in the swash-plate.
