Abstract: A discharge device for discharging electrical currents from a rotor having a shaft, the discharge device including a movable contact element at least partially accommodated in a guide having a guide wall and an outer wall, the contact element being configured to form an electrically conductive sliding contact between a sliding-contact surface of the contact element and a shaft contact surface of the shaft, the sliding-contact surface being intended to form the sliding contact, the contact element being connected to the guide and/or a support element in an electrically conductive manner, preloaded in the direction of the shaft contact surface by a spring element, and at least partially wetted with an oily fluid. At least one conduit for the oily fluid is provided in the guide, the conduit ending in the outer wall or being disposed in the outer wall of the guide.

Abstract: The invention relates to a fail-safe rotary actuator (1) for a coolant circuit, in particular for a coolant circuit of an internal combustion engine (2) having a plurality of sub-circuits (3) and (4), includes a coolant delivery pump (5) for circulating the coolant within the coolant circuit, and having a rotary-slide housing (8) which has a plurality of housing pass-through openings (6) and (7) and in which at least one rotary slide (9) having at least one rotary slide pass-through opening (11) and (12) is rotatably supported, wherein the housing pass-through openings (6) and/or (7) are fluidly connected to at least one sub-circuit (3) and/or (4), and can be brought into at least partial coincidence with the rotary slide pass-through openings (11) and/or (12) by a rotary motion of the rotary slide (9), wherein a thermostat valve (13) opens a flow path running parallel to the rotary slide (9) from one of the sub-circuits (3) or (4) to the coolant delivery pump (5), when a temperature limit of the coolant is e

Abstract: Coolant circuit, in particular a coolant circuit having a plurality of sub-circuits 1, 2, 3 of an internal combustion engine 11 includes a primary cooling circuit 1 and a heating circuit 2 as well as a coolant delivery pump 5 disposed on a rotary actuator 4, with the rotary actuator 4 having a rotary-slide housing 20 with several ports 8a, 8b, 9a, 9b, 10a through which coolant can flow, and a first and at least one second rotary slide 6 and 7 which are rotatably supported in the rotary-slide housing 20 and have each at least one rotary-slide pass-through opening 8, 9, 10 forming a flow path, wherein the ports 8a, 8b, 9a, 9b, 10a can be brought into at least partial coincidence with the rotary-slide pass-through openings 8, 9, 10 by a rotary motion of the respective rotary slide 6 and/or 7), wherein a first branch 1a of the primary cooling circuit 1 leads from the internal combustion engine 11 via a main radiator 12 to a main radiator port 8b of the first rotary slide and can be controlled by the first rotary
