Abstract: An air routing system includes an air filter for cleaning intake air having a clean air outlet a compressor for compressing aspirated intake air an intermediate line connected between the clean air outlet of the filter and the compressor, and an intake module. The intake module includes a plenum with a clean air inlet for compressed intake air at least one intake pope connected to the plenum and a bypass line for excess compressed filtered air. The bypass line has an inlet to a channel segment of the intake module for uncompressed clean air upstream of the compressor, and the bypass line is at least partly integrated into the intake module such that a volume of the bypass line at least partly surrounds the plenum.

Abstract: An insert filter 10 for cleaning a gas stream, particularly for the intake air of an internal combustion engine or an air-conditioning unit, which includes a filter frame 11, a filter element 12 placed in the filter frame 11, and a shaft cover 13 and which is placed in the shaft 14 of a duct system 15 that guides the gas stream such that an unfiltered side 16 is separated from a clean side 17 by the filter element 12 and the filter frame 11. The shaft cover 13 closes a shaft opening 24 through which the insert filter 10 is inserted in the shaft 14. The filter frame 11 is connected to the shaft cover 13 so that the filter frame 11 can be removed from the shaft 14 without any need for additional removal aids by simply pulling on the shaft cover 13.

Abstract: An air routing system, especially an air intake system of an internal combustion engine, which makes optimal use of available installation space by integrating a bypass channel (25) into an air intake module (10). The volume of the bypass channel also provides an acoustic shield for the collector chamber or plenum (22). The free area (13) behind the mounting flange (11) that is required for screwing in mounting bolts in order to mount the air intake module (10) is used by an air intake hood (14) which can be installed on the filter housing (15) after the air intake module has been mounted. This assures that there is a greater volume available in the filter housing (15), thereby reducing the noise at the inlet opening of the air intake module.

Abstract: A filter with housing including a filter element (12) shaped as a round cartridge, a housing (10) and a housing lid (11). The housing has a raw air inlet (19) and a clean air outlet (20). The clean air outlet is provided with a connecting support (16) on which the filter element (12) is arranged. The filter element has a radial gasket on its side that faces the connecting support and is guided by the housing at its side opposite from the connecting support.

Abstract: The invention is directed to an electronic multidigit display device illuminatable by means of light sources intended for a taximeter for indication of a trip price, of a possibly occurring surcharge as well as for superposition of stored data. The display device (3) is composed of a transflecting liquid crystal display (37) (LCD), a frame (38) as a common receptacle of the liquid crystal display (37) and a light conducting plate (43) and contact elements (39) for electrically connecting the liquid crystal display (37) with actuation lines (40) on a printed circuit board (2) and a hood (42) surrounding the frame (38) and provided with detent elements (41). By means of the hood (42) the complete display device (3) can be plugged into the printed circuit board and detented with same in a correct position with simultaneous completion of all line connections. The display device (3) is designed as a component intended specifically for the printed circuit board and for application in a taximeter device.

Abstract: An arrangement for the control of the quantity of the functions to be called in an electronic taximeter. In order to be able to adapt the device to the most multipurpose of demands, a greater or fewer number of recesses with keys A1 to A8 or with corresponding fill-in pieces can be provided in a key strip in a taximeter housing. A switch K1 through K8 is assigned to each key A1 through A8; the key information is supplied to the electronics and releases different key interrogation programs according to the number of keys present. With a smaller quantity of keys, several functions are assigned to the keys partially; with a larger quantity of keys, each key preferably releases only one function.

Abstract: A taximeter assembly including an electronic calculating module with data memory, an operating keyboard, as well as a data indicating device, consists of two flat housing panels which are joined by detent devices and which are secured together by a lead-sealable screw connection. An electronic taximeter circuit wired on a single printed circuit board is installed between the housing panels and feed-in of all electrical transmitter lines and supply lines is effected, as desired, from the rear or from below, wherein the latter are guided directly to connectors on the printed circuit board. The rear wall of the rear housing panel is constructed, at the same time, as a mounting plate for installation in a vehicle. A compact, extremely flat taximeter device having its circuitry in a single printed circuit board system enables arrangement of the device in an optimal installation position within or on the outside of the dashboard of a vehicle.

Abstract: A taximeter housing is securable to a vehicle part in such a manner that only two seals are required to prevent unauthorized tampering with the input connections, the interior components of the taximeter and the taximeter mount, and that only a single seal need be broken when it is necessary to gain access to the interior components to readjust the taximeter for a tariff change.

Abstract: A digital taximeter provides a visual read out of a first and a second multi-digit number. Instead of a plurality of discrete one-digit illuminated-digit display units arranged together to be capable of displaying multi-digit numbers, use is made of a single multi-digit illuminated-digit display unit having a row of equal-size digit zones. One or more of the middle ones of the digit zones are blocked from view to form a first and a second group of digit zones respectively adapted for the display of the first and the second multi-digit numbers and located to either side of the digit zones which are blocked from view. Although the digit zones are actually all of the same size, those of the first group are made to appear larger than those of the second group, in correspondence to the greater importance of the fare indication compared to the extra-charge indication.
