  • Patent number: 9671022
    Abstract: The invention relates to known housing seals of two housing parts lying against each other, a first housing part (1) having a first sealing surface (6) and a second housing part (2) having a second sealing surface (7), which housing seals are equipped with a seal (15), which is inserted into a groove (10) in the first sealing surface (6) of the first housing part (1), wherein the groove (10) is covered by the second sealing surface (7) of the second housing part (2). According to the invention, in order to prevent crevice corrosion, the groove (10) has an opening (11) between the sealing surfaces (6, 7), which is used to ventilate the groove (10) having the inserted seal. The invention is intended for water pumps, in particular for auxiliary water pumps of motor vehicles.

  • Patent number: 6388409
    Abstract: An electronically commutatable motor is described, the stator field windings of which can be connected to a commutation frequency having a DC supply voltage to generate a rotating field for the permanent magnet rotor and can be disconnected from it, the field windings being switchable via semiconductor output stages which can be activated via control signals with the commutation frequency of a control unit and whose operating conditions change as a function of a specified or specifiable setpoint. The disadvantages of motors with pulse-width-modulated control of the field windings can be avoided with simplified motor control in that the DC supply voltage is supplied to a DC transformer whose output voltage for the semiconductor output stages with the field windings changes as a function of the setpoint and that the control unit fully activates the semiconductor output stages continuously with unclocked control signals with the commutation frequency independently of the setpoint.

  • Patent number: 6307187
    Abstract: A method of operating a resistance heating element and a device for carrying out the method are described. During a first step, the resistance of a resistor of the resistance heating element is determined at a known base temperature. In a second step, the resistance setpoint value is determined as a function of resistance of the resistor at the known base temperature and known temperature coefficients. The resistance heating element is activated by approximately setting the resistance setpoint value in order to heat the resistance heating element to the given setpoint temperature.
