摘要:
A fuel injection apparatus having at least one solenoid valve for controlling the fuel injection that is contained in a housing part and a solenoid assembly having a magnetic coil and a magnet armature inserted into a recess of the housing part. A cover piece that can be attached to the housing part fixes the solenoid assembly in the housing part. A spring element is disposed between the cover piece and the solenoid assembly and clamps the solenoid assembly in the housing part. At least one securing element is formed onto the spring element and is of one piece with it, which secures the spring element to the housing part and secures the solenoid assembly in the recess of the housing part without the cover piece being attached to the housing part.

摘要:
A heat exchanger, preferably an oil cooler (1) for a motor vehicle, comprises stacked flat tubes (2, 3, 4), which have tube ends with apertures for admitting and discharging oil, which flows through the flat tubes (2, 3, 4) in their longitudinal direction. The apertures of adjacent flat tubes (2, 3, 4) are in fluid communication with one another in order to form flow passages, and spacings are left between the flat tubes for a medium, in particular a cooling medium, to pass through. The flat tubes are designed as extruded multi-channel tubes.

A fuel injection pump for internal combustion engines is proposed, the work chamber of which has a relief channel which is controllable via an electromagnetically actuatable valve, the movable valve element of which is urged in a closing direction by means of the pressure which prevails in the pump work chamber.

Hearing apparatus and especially hearing devices are to be designed to be smaller. To this end there is provision for the shell or otoplastic to be worn in the auditory canal or for the housing of the hearing apparatus to be made of battery layers, so that the shell or otoplastic or the housing of the hearing apparatus itself represents the battery. Alternatively the hearing device battery can also be relocated from a conventional hearing device into a normal otoplastic, with this also reducing the volume of the hearing device. The reduction in volume allows the acceptance of wearing the hearing device to be greatly increased, and a variant of the hearing apparatus can be more easily implemented as a cymba device.

A diagnostic article, in particular for medical applications, includes a microneedle array and a holding device supporting the microneedle array. The holding device is designed as a glove. The diagnostic article further includes a data recording device connected to the microneedle array, a data evaluation device connected to the data recording device, and a display device arranged on the holding device and connected to the data evaluation device.
摘要:
In a fuel injection pump with a housing, a metering pump and an injection adjuster for the metering pump, in which the injection adjuster has a piston that is acted upon by a restoring spring, the starting performance of the internal combustion engine supplied by the injection pump is to be improved by providing a starting spring which acts on the piston and acts counter to the restoring spring.
摘要:
A pressure sensor has a housing in which at least two diaphragms are secured in such a manner that they include a volume which is filled with a hydraulic fluid. The incompressible hydraulic fluid serves to transmit pressure between the diaphragms. For introducing the hydraulic fluid one diaphragm is provided with an opening. A narrow tube is connected in fluid-tight manner to the edge of the opening. The hydraulic fluid is introduced through the initially still open end of the narrow tube. After the filling with hydraulic fluid the open end of the narrow tube is sealed in fluid-tight manner, for example by squeezing. The narrow tube can serve at the same time a force-transmitting or travel-transmitting member which connects the diaphragm to a force or travel sensor.
摘要:
The invention relates to a method for soldering an all-aluminum heat exchanger, particularly a coolant radiator (1) for motor vehicles with a collecting reservoir (2) inside of which an additional heat exchanger (4), particularly a transmission oil cooler is placed. The invention also relates to a heat exchanger produced according to this method. The invention provides that the additinal heat exchanger (4) is, according to the so-called Nocolok® method, firstly soldered separately in a vacuum before being soldered together with the all-aluminum heat exchanger (1). The additional heat exchanger (4) is attached to the collecting reservoir (2) only via connecting sleeves (5) and soldered nuts (7).
