TRM Series Radial Piston Motors
The 5 cylinders are supported in the motor casing by two trunnions each which allow the cylinders to swivel so the piston and cylinder remain aligned with the eccentric axis of the crank shaft as the shaft rotates.
The cylinders are made of high strength steel and are not part of the motor casing.
The piston is a single component which can be fully balanced and whose diameter is not restricted by other design parameters. This means that a large number of cylinder bore can be possible in any one motor series.
