Abstract: A flush valve includes an inlet, an outlet and a valve arrangement. The valve arrangement includes a first chamber, a second chamber that is partly delimited by a diaphragm, a conduit extending between and connecting the first chamber and the second chamber, and a third chamber that connects the inlet and the outlet of the flush valve and that is partly delimited by the diaphragm. The third chamber includes a valve member configured to control a fluid flow from the inlet to the outlet based on the position of the diaphragm, and a control mechanism arranged in the conduit. The control mechanism includes a stepper and a plunger. The plunger is biased towards an inactive position and is displaced towards an active position by the second pressure [P2] in the second chamber when the second pressure [P2] in the second chamber is greater than a threshold value [PT].

Abstract: A pump for pumping liquid, the pump including a drive unit and a heat sink arranged to carry off heat that is generated in the drive unit, the drive unit including a motor compartment that in the radial direction is delimited by a motor casing and that accommodates an electric motor having a stator, a coupling compartment that at least partly is delimited by a pump top casing and that accommodates a power supply component, an upper partition that is arranged between the motor compartment and the coupling compartment. The motor casing includes an outer jacket that is connected to and that in the axial direction extends between the upper partition and the heat sink, an inner stator housing that extends between the stator and the heat sink, and a gas filled gap that in the radial direction separates the outer jacket and the inner stator housing.

Abstract: An electrical motor for a submersible machine, including a stator unit having a stator core and a rotor unit that is rotatably arranged in the stator unit. The rotor unit includes a rotor core and at least one permanent magnet. The rotor core has an outer diameter that is smaller than an inner diameter of the stator core. The rotor unit includes a brake, the radially outer surface of which is inscribed on a circle having a diameter that is greater than the outer diameter of the rotor core. At least a part of the brake is arranged to abut against an inner surface of the stator core upon mutual axial displacement of the rotor unit and the stator unit. The brake is spaced-apart from the stator core when the rotor unit is in the mounted state in the stator unit.
