Abstract: A measuring device is proposed to measure the gas pressure of an atmosphere, whereby the measuring device is provided with a sensor to measure the pressure located in the interior of a housing which encloses the sensor. In addition a unit to control the measuring device and to evaluate the signals as well as a supply unit are installed in this housing. The housing itself is sealed off against the surrounding atmosphere and is provided with contacts on the housing for the exchange of data between the measuring device and a unit for the evaluation of measured values connected to it. The contacts are provided at the same time to ensure that the unit for the evaluation of the signal of the pressure sensor can be supplied with control signals from outside the housing.

Abstract: Drinking valves (11) are usually screwed into water supply lines (10). This type of connection involves relatively high outlay. The invention proposes a drinking valve (11) which has a casing (12) consisting of an acceptance part (14) and a connecting part (15), a snap-in connection (48) being arranged between the acceptance part (11) and the connection part (15). This snap-in connection (48) makes it possible to push the acceptance part (14) and the connecting part (15) simply and rapidly together. The connecting part (15) can be fastened to the water supply line (10) in some other manner, and in fact permanently if necessary, because the connecting part (15) can remain on the water supply line (10) for repair to the drinking valve (11) by simply releasing the snap-in connection (48).

Abstract: A gas stream monitor shall be provided that facilitates the adjustment of the reseat flow. The gas stream monitor consists of a gas-tight casing whose interior is equipped with a seat for a reseat body that is movable inside the casing and is kept in open position against the flow direction by weight and/or spring force, in which the flow cross-section, surface area of the reseat body and the forces are determined in such a manner that gas stream monitor leaves its open position at a defined value of the reseat flow and is moved towards the seat of the casing, so that the gas conduit is closed in the shut position, and has outside the casing at least one manipulator to adjust the spring pre-tension and/or the stroke of the reseat body. The gas stream monitor serves to automatically shut off gas conduits upon the occurrence of an inadmissible flow increase due to, e.g. a damaged gas conduit or a defective consumer.

Abstract: An electronically commutated motor has at least two winding phases (112, 114) which are wound together or otherwise inductively coupled. Current in each phase is controlled by a respective power transistor (124, 128). An integrated circuit controller (146) receives signals from a Hall sensor (118) and generates rotor position output signals (OUT1, OUT2) which are oppositely phased and are applied to the bases of the respective power transistors (124, 128) so that the power transistors never both conduct at the same time. Further, a pair of latching transistors (162, 172) and a pair of base drain resistors (164, 174), connected to respective bases of the power transistors (124, 128) are provided, in order to assure “soft” switching of the power transistors at low RPM, yet prompter switching and higher efficiency at high RPM. These additional components also ensure a sufficiently long current gap between switch-off of one power transistor and switch-on of the other power transistor.

Abstract: A piezo actuator (1) is disclosed that has a contact lug (20, 21) for the electrical contacting of an electrode (14, 15) of an actuator member (11). Due to an expansion and contraction of the actuator member, a mechanical stress occurs in the contact lug that is minimized in that the contact lug has a device for adapting the expanse to a dimension of the expansion and contraction. The device is, for example, a deformation material in the form of a wire weave. The piezo actuator is utilized for the drive of an injection valve in an internal combustion engine.
