Abstract
A sliding exhaust gas brake connected in the exhaust pipe of an engine in a motor vehicle. It includes a housing having a portion defining an exhaust gas passage and connected to the exhaust pipe at both ends thereof and a portion connected to the exhaust gas passage substantially at right angles thereto and defining a chamber in which a valve member is slidably disposed. A valve actuator has one end connected to a housing wall defining the end of the chamber. The actuator includes a piston and a piston rod extending into the housing through the housing wall and having one end on which the valve member is supported. A partition is provided in the housing for dividing the chamber into a first portion in which the valve member is slidably disposed and a second portion into which the piston rod extends. The partition has an opening aligned with the exhaust gas passage. The opening has an edge defining a valve seat on which the valve member rests when closing the exhaust gas passage. The valve member is slidable on the partition and is received into the first portion of the chamber when opening the passage. The first portion of the chamber is fluidally connected with the exhaust gas passage upstream of the partition.
