Abstract: A thermal energy storage system has an insulated housing defining an internal volume; a heat storing material contained in said internal volume; a first conduit arrangement configured to carry a first working fluid. The first conduit arrangement extending across said internal volume such that thermal energy is transferrable between the first working fluid and the heat storing material. A second conduit arrangement carries a second working fluid. The second conduit arrangement extends across the internal volume such that thermal energy is transferrable between the heat storing material and the second working fluid. The first working fluid and the second working fluid are fluidly separated from each other inside the housing. The first conduit arrangement and the second conduit arrangement are in contact with each other so that thermal energy is transferrable between the first working fluid and the second working fluid.

Abstract: The invention relates to a conduit system comprising a first conduit (2) having a first engagement portion (3), and a second conduit (12) having a second engagement portion (13), wherein the first conduit (2) and the second conduit (12) are adapted to be connected to each other by means of the first and second engagement portions (3, 13). The first and second engagement portions (3, 13) comprises a first and second slide surface (4, 14), respectively. Said slide surfaces (4,14) extend radially outwards and has an inclination of 20-90° to a respective longitudinal axis (A) of the respective engagement portions. Said conduit system (1) further comprises spring means (20) arranged to urge one of the first and second slide surfaces (4, 14) towards the other one of said first and second slide surfaces (4, 14). The present invention also relates to a vehicle being provided with such a conduit system and to a method of assembling a conduit system for a vehicle.

Abstract: The present disclosure relates to a valve assembly adapted to be located at least partially in a body of fluid for controlling fluid flow from the body of fluid to a fluid outlet port. The valve assembly has an extension in a first direction and includes a fluid inlet port having an extension at least partially in the first direction. The valve assembly further includes a valve member being movable in the first direction relative to the fluid inlet port between an open position, in which the fluid inlet port is adapted to provide a fluid communication between the body of fluid and the fluid outlet port, and a closed position, in which the valve member covers the fluid inlet port such that fluid communication between the body of fluid and the fluid outlet port via the fluid inlet port is prevented.
