  • the elastic spacers are dimensioned so that the relative movement between piston rod and piston arises only at undesirably high pressure, ie at too high a force of the throttle.
  • This relative movement between the piston rod and piston allows for a limited travel rear opening of the throttle valve, whereby the pressure in the exhaust pipe is reduced so far that the engine braking effect is still sufficient, but the reduced pressure can no longer lead to engine damage.
  • the means for generating the springback comprise a prestressed spring arranged within the cylindrical housing, which acts on the one hand on the piston rod and on the other hand on the piston.

  • a vehicle engine 1 is equipped with a turbocharger 2.
  • the turbocharger 2 comprises a turbine part 3, which is mechanically connected to a compressor part 4 via an intermediate drive shaft 5.
  • the exhaust gas from the vehicle engine 1 is passed through an exhaust pipe 6 to the turbine part 3 of the turbocharger 2 via an inlet 7.
  • the exhaust gas flow causes rotation of the drive shaft 5 to drive the compressor part 4.
  • the compressor part 4 sucks fresh air from the atmosphere through an air inlet 8 in order to make it available to the vehicle engine 1 via an inlet pipe 9 on the air inlet side.
  • engine braking means are arranged in the region of an exhaust gas outlet 10 of the turbocharger 2, which comprises an exhaust gas brake valve 11, which is designed in the manner of a flap valve.
  • the exhaust brake valve 11 is controlled by a control cylinder 12 of the engine brake actuated to bring about a deceleration function by throttling the exhaust gas flow on the exhaust side of the turbocharger 2 in the region of the exhaust gas outlet 10.
  • the engine brake valve 11 is connected in the exhaust outlet 10 by a lever for implementing the linear movement of the control cylinder 12 of the engine brake in a rotational movement for actuating the engine brake valve 11.
  • the control cylinder 12 of the engine brake is pivotally mounted on a support frame, which is arranged to one end of the control cylinder 12 of the engine brake.
  • the piston 14 divides the housing 13 into a spring chamber 16 for accommodating a return spring 17 for the piston rod 15 and a pressure chamber 18 for generating an actuating force by the piston 14 by compressed air.

  • the diameter of the piston 14 is to be dimensioned so that the force exerted by pressurization force is greater than the spring force of the return spring 17 and the actuating force of the - not shown here - throttle valve of the engine brake valve.
  • the diameter of the inner piston 25 is to be dimensioned such that the force exerted due to pressurization is equal to the remindöffhungskraft the throttle valve of the engine brake valve.
  • the operating pressure of the control piston 12 In order to keep the return force of the piston rod 15 to almost constant value, the operating pressure of the control piston 12 'must be kept within narrow limits. Since the Actuating pressure between cut-in pressure and cut-off pressure of the air supply system can change, even in special cases can fall to a backup pressure, it is advantageous if the actuation pressure is below the operating pressure range.

  • the cylindrical working space 26 is connected via a built-in piston 25 in the discharge valve 30 with the environment to limit the pressure in the working space 26 to a maximum value.
  • the drain valve 30 represents, for example, a check valve with an increased opening pressure to drain the excess pressure from the working space 26 of the air spring in the spring chamber 16.

  • an outwardly leading check valve 33 is arranged to remove excess pressure from the spring chamber 16 to the environment. As a result, the spring chamber 16 is protected against contamination from the outside.
  • a refill valve 34 is further integrated, which is arranged between the spring chamber 16 and the pressure chamber 18.
  • the refill valve 34 is the Working chamber 18 is only connected to the spring chamber 16 when the pressure difference is below a limit - for example, 1.6 bar -.
  • the refill valve 34 may be performed by the valve body as Elastomerbauteil.
  • the refill valve 34 prevents dirt from being sucked into the spring chamber 16 from the outside, since during return movement of the piston 14 the spring chamber volume becomes larger, which leads to a low pressure below the atmospheric pressure in the spring chamber 16. The low pressure prevents the return movement of the piston 14 and a suction effect, whereby dirt can be sucked from the outside. This is no longer to be feared due to the pressure compensation brought about by the refill valve 34.
