Title: Carburettor for internal combustion engines with temperature-compensated idling adjustment
Inventor: GERHARDY REINHARD
IPC: F02M17/40
Filed: 1981-07-11
Abstract: The invention relates to a carburettor for internal combustion engines with a continuous intake pipe (2) arranged in the housing (1) for the air feed and an outlet port (16) opening in the intake pipe for the fuel feed in the idling position. The passage cross-section of the admission orifice (30) to the outlet port (16) can be varied by means of a setting needle (32) adjustably held in the housing (1). For the same idling speed, the adjustment of the idling setting needle (32) when the engine is in the warmed-up state must be different from that when the engine is in the cold state so that during operation manual setting adjustments have to be made in order to keep the idling speed largely constant. According to the invention it is proposed to manufacture the setting needle (32) from a material, the temperature coefficient of which is greater than that of the material of the carburettor housing (1, Fig. 1). As the operating temperature varies the passage cross-section of the inlet orifice (30) is adjusted accordingly owing to the changes in length of the setting needle (32) so that the idling speed is largely constant irrespective of the operating temperature and manual setting adjustments are avoided. <IMAGE>

Title: Vane-cell compressor
Inventor: REMBOLD HELMUT DIPL ING
IPC: F04C18/344
Filed: 1982-11-03
Abstract: A vane-cell compressor is proposed, which serves in particular for activating a motor vehicle levelling system. The vane-cell compressor comprises a rotor, which is connected to a drive shaft and has radial slits in which movable vanes slide in a sealtight manner. The neighbouring vanes divide off individual delivery cells from one another, because they slide with their outside edges on the curved wall face of a cylindrical housing recess. The housing recess is designed in such a way that, in particular, two diametrically opposite sickle-shaped working spaces are produced, which lie between the housing recess and the rotor and each have at least an inlet opening and an outlet opening. The forward working space, with respect to the working direction of the rotor, has a greater volume than the working space alongside it in the working direction. The outlet opening of the larger working space is connected to the inlet opening of the smaller working space, so that two series-connected compressor stages are produced, which also allow relatively high compressions which cannot be achieved with the known single vane-cell compressors. <IMAGE>
