摘要:
The invention relates to a valve, especially a rotary piston valve (1), for controlling the temperature and quantity of the returned exhaust gas in internal combustion engines. Said valve comprises a valve housing (2) and a control element (3) disposed therein which interacts with a valve face (140 configured in the valve housings (2), the control element (3) having a conical surface area (10).

The invention relates to an exhaust gas heat exchanger comprising a bundle of pipes which consists of exhaust gas pipes and a bypass channel, and a housing which can be cross-flown by an aqueous cooling agent. The bundle of pipes and the bypass channel joins in a common exhaust gas inlet, wherein an exhaust gas valve is arranged for controlling the exhaust gas flow through the bundle of pipes or the bypass channel. According to the invention, the bypass channel is embodied as a special steel tube (10) comprising a covering (11) which is made of a high-temperature resistant plastic and wherein the housing, which can be cross-flown by the cooling agent, is arranged.

The invention relates to an exhaust gas heat exchanger (2) comprising a bundle of pipes (21) consisting of exhaust gas pipes (22) and a bypass channel (23) in a common housing. The pipe bundle is arranged in a first chamber that is crossflown by a liquid coolant and the bypass channel is arranged in a second, separate chamber. The pipe bundle and the bypass channel lead into a common exhaust gas inlet area and a common exhaust gas outlet area in which an exhaust gas valve actuated by a servo-drive is arranged, said valve guiding the exhaust gas flow through the pipe bundle or the bypass channel. According to the invention, the exhaust gas valve has a movable closing organ that is resistant to bending, said organ being preferably embodied as a pivoting semi-flap (27) that is fixed with a longitudinal side (28) to a drive shaft (30) that is arranged crosswise relative to the exhaust gas flow (A).

The invention relates to a heat exchanger for internal combustion engines, comprising a first elongated flow channel, for the passage of exhaust gases from the internal combustion engine, a second flow channel, arranged adjacent to the first flow channel, for passage of the exhaust gases, a line, separate from the second flow channel, for the passage of a medium, in particular, a coolant, whereby heat energy may be exchanged between the exhaust in the second flow channel and the medium in the line and heat energy may not be exchanged to a significant degree between the exhaust in the first flow channel and the medium in the line and a valve channel with an adjustable valve element, whereby a distribution of the exhaust gasses between the first flow channel and the second flow channel may be adjusted by means of adjustment of the valve. According to the invention, an advantageous heat exchanger with respect to the required fitted space and the exhaust flow may be achieved, whereby an input flow axis for the valve channel has a different flow axis from the flow axis of the first channel.

The invention relates to a heat exchanger for internal combustion engines, which comprises a first, elongate flow channel for the exhaust gases of the internal combustion engine to pass through a secured flow channel, adjacent to the first flow channel, for the exhaust gases to pass through, and a pipe separate from the second flow chamber, for a medium, especially a cooling agent, to pass through, whereby heat can be exchanged between the exhaust gas of the second flow channel and the medium in the pipe and beat can be exhausted at least to a substained degree between the exhaust gas in the first flow channel and the medium in the pipe. The heat exchanger also comprises a valve channel with an adjustable valve element the distribution of the exhaust gases to the best flow channel and the second flow channel being adjustable by a position of the valve element. The aim of the invention is to provide a heat exchange which repairs little space and which can be produced at low cost. For this purpose, the valve channel comprises a valve channel housing which can be assembled from a first housing element and at least one second housing element.
