Abstract: The disclosure relates to an electrical motor comprising a stator (101) being a stationary part in the electrical motor, the stator (101) having a plurality of poles mounted in a radial direction, a rotor (102) having a plurality of magnets and arranged to rotate freely around the stator (101), the stator (101) and the rotor (102) are moulded into an epoxy layer of a housing of the motor in such a way that a channel (106) is formed allowing a cooling medium flowing through the internal part of the electrical motor.

Abstract: Valve device for controlling the delivery of pressurized fluid from a common pump to two hydrostatic working motors, one of which is subjected to a load dependent on the speed of the other motor. A volume flow regulator is disposed in the flow path between an inlet port of the valve device connected to the pump and an outlet port connected to the other working motor and varies the volume flow rate in this flow path in inverse proportion to the pressure in the inlet port to keep that pressure substantially constant.
