Abstract: A control device and method for controlling a compression release brake arrangement is provided. The compression release brake arrangement comprises an exhaust valve actuator assembly, a first actuator valve and a second actuator valve. The method comprises controlling the first and second actuator valves to a first state in which one of the actuator valves is open and the other one is closed. The disclosure further relates to a computer program, a computer readable medium, as well as to a vehicle comprising the control device.

Abstract: A cooling system in a vehicle includes a cooling fluid pump (3) that circulates cooling fluid in the cooling system, a cooler (5) for the cooling of the cooling fluid, and a valve (10) to lead cooling fluid to the cooler (5) for cooling or to a return line (13) without cooling. A first circuit (6) includes cooling channels (6a) for the cooling of the combustion engine (1) and a second circuit (17) for the cooling of a hydraulic retarder. The first circuit (6) leads cooling fluid from the cooling fluid pump (3) to a first inlet (10c) at the valve (10). The second circuit (17) leads cooling fluid to a second inlet (10d) at the valve (10). In operating conditions in which the hydraulic retarder is not activated, the valve (10) blocks the second inlet (10d) and thus the circulation of cooling fluid through the second circuit at the same time that it receives cooling fluid from the first circuit (6) through the first inlet (10c).
