Fig. 1: The Hägglunds VI motor
The symmetrical design of the motor has made it possible to construct it as a
2-speed motor. This means that two different speeds are obtained for a given flow.
The simplest way of performing displacement change over is by connecting a spe-
cial valve, known as a 2-speed valve, direct to the connecting flange on the cy linder
block.
The motor is designed so that pressure pulsations in the motor case are avoided.
This has the advantage that impurities are not sucked into the case.
