Abstract
A control device is provided for uniformly distributing gases and/or liquids between at least two containers with a different internal pressure, such as, fuel containers, crank casings and the like, in particular in internal combustion engines with more than one cylinder bank and a separate intake air feed per bank. The gas feed line assemblies (1) leading to the cylinder banks are connected to a chamber of a double-acting pressure box (4) and the gas flow in the gas feed line assembly (1) with the greater underpressure is reduced using a diaphragm (7) that is deflected as a result of a pressure difference in the gas feed line assemblies (1) by means of at least one throttle valve (10, 11) that can be activated via at least one sliding element (8, 9).
Claims5
A control device for uniformly distributing gases and/or liquids between at least two fuel containers or crank casings having different internal pressures and communicating with an internal combustion engine having more than one cylinder bank and a separate intake air feed per bank, comprising:
- gas feed line assemblies leading to the cylinder banks;
- a double-acting pressure box having a chamber connected to the gas feed line assemblies;
- a diaphragm in the chamber and disposed to deflect as a result of a pressure difference in the gas feed line assemblies;
- at least one sliding element connected to the diaphragm and moving in response to deflection of the diaphragm;
- and at least one throttle valve connected to the at least one sliding elements, the at least one throttle valve reducing a gas flow in the gas feed line assembly having a greater underpressure.
