摘要： A fluid pump, in particular a water pump, has a pump housing (11) that surrounds a pump wheel and a motor housing, connected to the pump housing, in which an electric motor (21) driving the pump wheel is received along with a stator (22) and rotor. For the sake of sealing off the pump from the escape of fluid and sealing off the motor housing from the penetration of fluid, with only one seal, and with assembly of the fluid pump without additional connecting elements, the pump housing (11) has a lower housing part (12) with an annular rib (14) protruding radially outward, and an upper housing part (13) slipped onto the lower housing part (12). Between the free annular face end of the upper housing part (13) and the annular rib (14), there is a sealing ring (15). The motor housing is embodied as a housing pot (26), which with a gripping edge (28) fits over the annular rib (14), sealing ring (15), and part of the upper housing part (13), and is locked to the upper housing part (13), producing an axial clamping force (FIG. 3).

摘要： 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.

摘要： In a constant timing valve for the discontinuous metering of a volume flow, in particular the flow of cooling water flowing through a heat exchanger of a motor vehicle heater, the volume flow flowing through the valve outlet (17) is maintained constant regardless of the magnitude of the volume flow available at the inlet (16) in the valve housing (15) in that a bypass channel (28) is formed which leads from the inlet (16) to a return (18) and is closed by a spring-loaded, pressure-contro led bypass valve (29). The bypass valve (29) is designed in such a way that the excess volume flow flows off via the return (18) when the connection between the inlet (16) and outlet (17) is not blocked, at least after reaching a given minimum pressure in the bypass channel (28). The integrated bypass valve (29) is coupled with the timing valve (14) in such a way it is compulsorily pushed opened by the timing valve (14) when the timing valve (14) is closed (FIG. 1).

摘要： An electrical connection arrangement between a contact element (13) and connection wire (12)is designed in such a way that reliable contact-making is possible in a simple manner and with the capability of automation. For this purpose, the connecting arrangement has a receptacle (11), in which the connecting wire (12) is held in the form of a winding having a plurality of turns. The contact element (13) provided with cutting edges (32) can be plugged into the receptacle (11). The outer delimitations of the turns of the connecting wire (12) and the cutting edges (32) are inclined with respect to one another in their longitudinal extent, with the result that, in the case of a plug-in movement of the contact element (13) into the receptacle (11), said contact element enters into a cutting connection on a plurality of turns of the connecting wire (12). This connection arrangement is used, inter alia, when contact is made between the connecting wires (12) of coils.

摘要： A rotor according to the prior art has a top part and a bottom part, where the bottom part has stays that are mechanically connected to the top part. However, this has the disadvantage that very strict tolerances must be respected and the type of fastening is not secure. A rotor according to the invention has a ring, which presses stays and thus, by means of positive and frictional engagement, magnets against a tubular element, which in turn is disposed on a bottom part. The bottom part, together with a rotor shaft and a top part, constitutes a rotor.
