Abstract
Abstract In a combustion engine for motor vehicles a cylinder arrangement having a combustion chamber and a precombustion chamber in communication therewith and receiving the spark-plug with its electrodes, a first fuel supply or dosing arrangement opening into the combustion chamber and a second fuel supply or dosing arrangement opening into the precombustion chamber, an operating means associated with the first and second fuel dosing means and having a member following the different predetermined positions representative of the operating state of the first fuel supply or dosing arrangement, such member being constructed to define the operating state of the second fuel supply or dosing arrangement, wherein such member comprises a stem assuming different and predetermined axial positions and having a cross sectional profiling thereon, means coupled to the cross sectional profiling and defining the predetermined operating states of the second fuel dosing arrangement, and wherein further the cross sectional profiling is formed as a cam, an operating bar slidably mounted against the force of a spring transversely with respect to the stem, the camming being operatively coupled with such bar which in turn is operatively coupled with the second fuel supply or dosing arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
In a combustion engine for motor vehicles, a cylinder arrangement comprising a combustion chamber, a precombustion chamber in communication with said combustion chamber, spark-plug means having electrodes in communication with said precombustion chamber, a first fuel supply or dosing means associated with said combustion chamber and a second fuel supply or dosing means associated with said precombustion chamber, an operating means associated with said first and second fuel supply or dosing means, said first fuel supply or dosing means comprising a member assuming different predetermined positions representative of the operating states of the first fuel supply or dosing means and including a stem following the different and predetermined axial positions and having a cross sectional profiling thereon, said operating means comprising fluid moving means coupled with said second fuel supply or dosing means, and further comprising a pressure translating conduit coupled to a pressure chamber and to the cross sectional profiling of the stem.
Claim 2
Dependent Claim
154 words
In a combustion engine for motor vehicles, a cylinder arrangement comprising a combustion chamber, a precombustion chamber in communication with said combustion chamber, spark-plug means having electrodes in communication with said precombustion chamber, a first fuel supply or dosing means associated with said combustion chamber and a second fuel supply or dosing means associated with said precombustion chamber, an operating means associated with said first and second fuel supply or dosing means, said first fuel supply or dosing means comprising a member assuming different predetermined positions representative of the operating states of the first fuel supply or dosing means and including a stem following the different and predetermined axial positions and having a cross sectional profiling thereon, said operating means comprising fluid moving means coupled with said second fuel supply or dosing means, and further comprising a pressure translating conduit coupled to a pressure chamber and to the cross sectional profiling of the stem.
Claim 3
Dependent Claim
61 words
The cylinder arrangement as claimed in claim 1, wherein said cross-sectional profiling includes valve means in the form of a two-way valve and said fluid moving means including a membrane which at an actuated condition of said first fuel supply or dosing means connects said pressure translating conduit with said pressure chamber, and under other conditions connects it with the atmosphere.
Claim 4
Dependent Claim
178 words
In a combustion engine for motor vehicles, a cylinder arrangement comprising a combustion chamber, a precombustion chamber in communication with said combustion chamber, spark-plug means having electrodes in communication with said precombustion chamber, a first fuel supply or dosing means associated with said combustion chamber and a second fuel supply or dosing means associated with said precombustion chamber, an operating means associated with said first and second fuel supply or dosing means, said first fuel supply or dosing means comprising a member assuming different predetermined positions representative of the operating states of the first fuel supply or dosing means and including a stem following the diffeRent and predetermined axial positions and having a cross sectional profiling thereon said second fuel supply or dosing means including a valve and said operating means including a pressure translating conduit leading to a mixture forming device, such as a carburetor, and which at the same time forms a mixture conduit, said cross sectional profiling being in the form of a valve or a pump which is placed in the pressure translating conduit.
Claim 5
Dependent Claim
178 words
In a combustion engine for motor vehicles, a cylinder arrangement comprising a combustion chamber, a precombustion chamber in communication with said combustion chamber, spark-plug means having electrodes in communication with said precombustion chamber, a first fuel supply or dosing means associated with said combustion chamber and a second fuel supply or dosing means associated with said precombustion chamber, an operating means associated with said first and second fuel supply or dosing means, said first fuel supply or dosing means comprising a member assuming different predetermined positions representative of the operating states of the first fuel supply or dosing means and including a stem following the diffeRent and predetermined axial positions and having a cross sectional profiling thereon said second fuel supply or dosing means including a valve and said operating means including a pressure translating conduit leading to a mixture forming device, such as a carburetor, and which at the same time forms a mixture conduit, said cross sectional profiling being in the form of a valve or a pump which is placed in the pressure translating conduit.
Claim 6
Dependent Claim
18 words
