Abstract:
An injector having an injector body to which a fuel line is connected for delivering fuel at high pressure. A filter bore is formed in the body and a fuel filter is disposed, through which filter the delivered fuel flows. A sealing seat is formed in the filter bore against which seat the end of the fuel line is pressed upon fastening of the fuel line to the injector body. The filter bore discharges at the outside of the injector body. The sealing seat is disposed with its longitudinal axis inclined to the longitudinal axis of the filter bore, and in the injector body, a bore extending at least approximately coaxially to the sealing seat is provided, into which the end region of the fuel line plunges. By the end region, plunging into the bore, of the fuel line, an outer end region of the filter bore, discharging at the outside of the injector body, is separated from an inner end region, subjected to high pressure, of the filter bore, and the fuel filter is disposed in the inner end region of the filter bore.
Abstract:
A belt tensioner for safety belt arrangements in motor vehicles has a holder (11) on which are provided a belt winding reel (12) with a safety belt (13) coiled thereon, a blocking arrangement and an additional drive (15) connected via clutch (20) to the belt winding reel (12). The additional drive (15) contains a pressure source (16) which abruptly builds up a high pressure in a pressure chamber on being triggered and also contains a torque generating device (18) acted on by the pressure in the pressure chamber (17) and a drive shaft (19) connected to the latter. The drive shaft (19) is rotationally fixedly connectable to the belt winding reel (12) via the clutch (20). The torque generating device (18) includes a flexible draw band (21) which is secured at one end at a first mounting point (25) to the periphery of the drive shaft (19) or to the drive reel (22) concentrically mounted thereon and is partially wound onto the drive shaft (19), or onto the drive reel (22) and is secured at the other end, at a second mounting point (26) to the peripheral wall (30) of a band running chamber (23) within a housing (24). Pressure applied to the draw band causes belt tensioning movement of the drive shaft (19) or drive reel (22).
Abstract:
The invention relates to a method for operating a steam cycle process for using the heat of an internal combustion engine (2), comprising a conduction circuit (4) in which a working medium circulates. Said conduction circuit (4) comprises at least one pump (6, 13), at least one heat exchanger (8), an expansion machine (10), a feedwater tank (14) for storing the liquid working medium, and a condenser (12). Components of the conduction circuit (4) are frost-proofed by partially evacuating the liquid working medium. After the end of the circulation of the working medium, at least one of the pumps (6, 13) continues to operate in order to evacuate the working medium at least from the pump (6, 13) which continues to operate.
