A solenoid valve is proposed, having a substantially circular cross-sectional shape orthogonally in relation to an effective axis of the solenoid valve, it being possible for valve devices of the solenoid valve to be connected to one another by means of joining operations directed substantially in the direction of the effective axis, the valve devices having such peripheral shapes that the valve devices can be centered with respect to one another by means of the joining operations.

Solenoid valve

A fluid pump, in particular a water pump, has a pump housing () that surrounds a pump wheel and a motor housing, connected to the pump housing, in which an electric motor () driving the pump wheel is received along with a stator () 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 () has a lower housing part () with an annular rib () protruding radially outward, and an upper housing part () slipped onto the lower housing part (). Between the free annular face end of the upper housing part () and the annular rib (), there is a sealing ring (). The motor housing is embodied as a housing pot (), which with a gripping edge () fits over the annular rib (), sealing ring (), and part of the upper housing part (), and is locked to the upper housing part (), producing an axial clamping force (FIG.).

A stator according to the prior art is formed out of a laminated stack that is insulated by means of a plastic coating, and stator pole teeth are connected to each other in permeable fashion. A stator () according to the invention comprises separate permeable stacks of individual laminations () that are held together by means of a plastic coating. The return ring () is joined with play on the stack of individual laminations () and installed on the stack via bayonet coupling.

Stator

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.

Rotor

The invention relates to a valve, in particular for the fluid circulation in a motor vehicle, having a housing ( ) with at least one inlet ( ) and at least one outlet ( ) that communicate with one another via a passage ( ), and having a valve member ( ), which is embodied as a movable flap ( ) that monitors the passage ( ), wherein the passage ( ) has a chamber ( ) in which the flap ( ) is disposed and into which the at least one inlet ( ) and the at least one outlet ( ) discharge, wherein the flap ( ) is pivotably supported in the housing ( ) and can be shifted via a drive mechanism ( ) from a first terminal position ( ) to a second terminal position ( ), and wherein the terminal positions ( ) form an angle (&agr;) that is smaller than 90&deg;.

Valve

A stator ( ) and sleeve ( ) are secured to one another by means of nonpositive engagement in the form of a bayonet mount ( ). The apparatus is employed in particular in electric motors.

Device with a stator and a sleeve

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.

Electronically commutatable motor

A magnetic valve for a fluid-controlled heating and/or cooling installations has a valve housing, an electromagnetically switched valve member which in a first fixing position makes a connection between an inlet conduit and an outlet conduit and in a second switching position blocks the connection, a valve shaft provided with an armature and connected movably to the valve member, the valve shaft having a side which faces the valve member and is provided with a unit for slowing down a speed of the valve shaft upon closure of the valve member, the valve housing and the valve member being arranged so that a flow direction of a fluid around the valve member is opposite to a closing direction of the valve member.
