Abstract

Abstract A connecting line between the compressor of an exhaust gas turbocharger and a suction pipe of an internal combustion engine. For the compensation of tolerances and for the installation simplification, the connecting line includes at least two nested pipe sections disposed one within the other and cooperating by way of sealing means; the pipe sections are connected with each other by means of a disengageable device including a bridge.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 102 words
A turbocharged internal combustion engine having a connecting line between the compressor of the exhaust gas turbocharger and a suction pipe means of the internal combustion engine, characterized in that the connecting line includes at least two nested pipe sections, one disposed within the other, wherein said two pipe sections can be secured together in any one of a number of differently extending telescoped positions by way of sealing means, said pipe sections being rigidly connected with each other in any one of said telescoped position by a connection means having disengageable means to secure said connection means to said pipe sections.
Claim 2
Dependent Claim 102 words
A turbocharged internal combustion engine having a connecting line between the compressor of the exhaust gas turbocharger and a suction pipe means of the internal combustion engine, characterized in that the connecting line includes at least two nested pipe sections, one disposed within the other, wherein said two pipe sections can be secured together in any one of a number of differently extending telescoped positions by way of sealing means, said pipe sections being rigidly connected with each other in any one of said telescoped position by a connection means having disengageable means to secure said connection means to said pipe sections.
Claim 3
Dependent Claim 28 words
A connecting line according to claim 1, characterized in that the connection means is formed by two profiled half-shells which are supported at the pipe sections by flanges.
Claim 4
Dependent Claim 22 words
A connecting line according to claim 2, characterized in that the pipe sections have identical diameters within the area of the flanges.
Claim 5
Dependent Claim 29 words
A connecting line according to claim 3, characterized in that the disengageable means are formed by cooperating threaded means and clamping bands, provided within the area of the flanges.
Claim 6
Dependent Claim 40 words
A connecting line according to claim 4, characterized in that the connecting line extends at least section-wise transversely to the internal combustion engine above a valve cover and in that one pipe section is securely retained at the valve cover.
Claim 7
Dependent Claim 48 words
A connecting line according to claim 5, in which the exhaust gas turbocharger is flangedly connected to an exhaust pipe below a cylinder head near the area of a crankcase, and characterized in that the other pipe section extends angularly shaped between the connection means and the compressor.
Claim 8
Dependent Claim 29 words
A connecting line according to claim 1, characterized in that the disengageable means are formed by cooperating threaded means and clamping bands, provided within the area of the flanges.
Claim 9
Dependent Claim 40 words
A connecting line according to claim 1, characterized in that the connecting line extends at least section-wise transversely to the internal combustion engine above a valve cover and in that one pipe section is securely retained at the valve cover.
Claim 10
Dependent Claim 29 words
A connecting line according to claim 8, characterized in that the disengageable means are formed by cooperating threaded means and clamping bands, provided within the area of the flanges.
Claim 11
Dependent Claim 48 words
A connecting line according to claim 1, in which the exhaust gas turbocharger is flangedly connected to an exhaust pipe below a cylinder head near the area of a crankcase, and characterized in that the other pipe section extends angularly shaped between the connection means and the compressor.
Claim 12
Dependent Claim 28 words
A connecting line according to claim 10, characterized in that the connection means is formed by two profiled half-shells which are supported at the pipe sections by flanges.
Claim 13
Dependent Claim 22 words
A connecting line according to claim 11, characterized in that the pipe sections have identical diameters within the area of the flanges.
Claim 14
Dependent Claim 182 words
A turbocharged internal combustion engine having a connecting pipe between the compressor of the exhaust gas turbocharger and a suction pipe of an internal combustion engine, the connecting pipe having at least two pipe sections, a connection means between said sections and held to said sections by means of detachable devices, said pipe sections being slideable into one another so that angular and axial tolerance can be balanced, a sealing device arranged in a groove provided between a receiving part in one of said pipe sections and a connecting part in the other of said pipe sections, the connection means being formed by two profiled half shells having flanges, which flanges are supported at the pipe sections, the half shells being fastened at the pipe sections by the detachable devices in such a way that the half shells represent a body that surrounds the pipe sections almost on all sides and rigidly connect the pipe sections, said pipe sections having the same diameters in the area of the flanges, and wherein the detachable devices are provided in the area of the flanges.
