Abstract
The apparatus comprises two hydraulic motors to which two displacement members in line are respectively coupled. Each of the motors has three main connections, namely one main connection that is common to both of its cylinder capacities, and two main connections, one for each of its two cylinder capacities. The first main connection of the first motor is connected to the fluid feed and the first main connection of the second motor is connected to the fluid return. The two main connections of the motors are interconnected. A selector having at least two positions is connected to the fluid feed, to the fluid return, and to the third main connection of at least one of the motors. For each of the two selector positions, the total cylinder capacity fed by the pump differs.
