摘要： A filter for continuous filtration of a liquid includes conventionally a vessel having a center shaft on which is arranged at least one rotating filter element defining an inner space for liquid obtained at filtration. Further there is provided a washing device for washing of material deposited on the filter element, a connection between said inner space and outlet means from said vessel and a separator connected to said outlet and adapted for separating filtrate and gas. Means is provided outside said vessel for generating an overpressure in the gas space of the vessel and a lower pressure in the interior of the filter element at least corresponding to the evaporating temperature of the filtrated liquid for evaporation of the liquid in the separator. The separator is provided with a cooling device for cooling the separated gas and an outlet for condensate obtained at cooling.

摘要： An engine brake system and a method for controlling the exhaust gas pressure of an exhaust system for a vehicle provided with an engine are provided. The system includes a main exhaust gas conduit connected to the turbine of a turbo arrangement and an Exhaust Pressure Governor (EPG) which is used to create a backpressure in the exhaust system so as to function as an engine brake. The turbo arrangement includes a Variable Geometry Turbine (VGT). The Exhaust Pressure Governor is located in a bypass conduit which is connected to the main exhaust conduit upstream the connection to the turbine of the turbo arrangement and the main exhaust conduit includes a valve arrangement downstream the bypass conduit connection for closing the main exhaust conduit. According to the method for controlling the system, the flow passage through the main conduit is open and the flow through the bypass conduit is closed in response to an output control indicating that no engine braking is desired. In case there is an output control indicating that engine braking is desired, the flow passage through the main conduit is closed and the flow through the bypass conduit is open whereby the EPG is controlled to provide a desired backpressure according to the control signals from the control system.
