Control device for uniformly distributing gases and/or liquids between at least two containers

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).

Claims

1. 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.

2. The control device of claim 1, wherein the at least one sliding element comprises two opposed sliding elements and wherein the at least one throttle valve comprises two opposed throttle valves connected respectively to the two opposed sliding elements.

3. The control device of claim 1, wherein the diaphragm is a spring-elastic diaphragm.

4. The control device of claim 1, wherein the diaphragm is suspended by at least one spring.

5. The control device of claim 1, wherein the diaphragm is suspended by springs on both sides.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) The FIGURE is a schematic illustration of a control device in accordance with the invention.

DETAILED DESCRIPTION

(2) Gases from the crank casing venting or the fuel tank venting downstream of the throttle valve are fed via gas feed lines 1 into the combustion gas intake system 2 of a first cylinder bank and in parallel into the combustion gas intake system 3 of a second cylinder bank. Pressure differences in the combustion gas intake systems 2 and 3 of the two cylinder banks are detected by a double-acting pressure box 4 that is connected to the gas feed line assemblies. A diaphragm 7 is suspended from springs 5 and 6 and is deflected from a normal position in the event of a pressure difference between the combustion gas intake systems 2 and 3. The deflection of the diaphragm 7 causes movement of sliding elements 8 and 9, and this movement of sliding elements 8 and 9 activates throttle valves 10 and 11 in the gas feed line assemblies 1 leading to the cylinder banks 2 and 3. This configuration ensures uniform distribution of the gases additionally introduced into the intake air, between the two cylinder banks.
