The invention relates to a valve (), in particular an expansion valve, for controlling fluid flow, having a valve central housing () having a first and a second opening () and a valve element () which has a rotationally symmetrical outline and is arranged rotatably within the valve element housing (). According to the invention, the valve element () has a cut-out, wherein the cut-out () has a variable dimension, and a sub region () of the cutout () is formed continuously through the valve element ().

Valve for controlling a fluid flow

A distribution valve comprises: a housing, and a spool in the housing, the spool mounted in a valve chamber so as to be rotatable along an axial axis, and the spool comprising a sidewall comprising a first spheroidal segment and a second spheroidal segment, a spool first port in the first spheroidal segment, and a spool second port in the second spheroidal segment; and an intermediate member mounted between the housing and the spool and fixed relative to the housing and in sliding contact with the sidewall of the spool in a sealed manner, wherein a first valve port is defined when the spool first port and an intermediate first port overlap, and a second valve port is defined when the spool second port and an intermediate second port overlap, wherein a degree of opening of the valve ports changes as the spool rotates relative to the housing.

Distribution valve and refrigeration system

The invention relates to an adjustment device () for a rotating body (), in particular a fan () of a cooling fan for a combustion engine, or a shaft () or a rotor () of an electric motor (), comprising a rotation axis (R), wherein a mass () that rotates around the rotation axis (R) can be dislocated relative to the rotation axis (R) by means of the adjustment device (). The invention further relates to a rotating body (), in particular a fan () of a cooler blower for a combustion engine, or a shaft () or a rotor () of an electric motor (), comprising an adjustment device () according to the invention.

Adjustment device for a rotating body and rotating body

The invention relates to an electric motor assembly, particularly for driving a fan for an engine cooling system and/or an air conditioner of a motor vehicle, comprising an electric motor and a motor control device for activating the electric motor. According to the invention, the motor control device can be adjusted according to a characteristic curve () of the electric motor and/or of the fan, and thereby the power and/or rotational speed of the electric motor can be adjusted.

Electric motor assembly, method for operating an electric motor, and motor control device

The invention relates to an engine fan device for a vehicle, characterized in that the engine fan device () has at least one or more receiving contours (), in which one or more balancing elements () can be received, wherein at least one receiving contour () has at least two planes (), and/or wherein at least two receiving contours () each have at least one plane (), wherein both planes () are different from each other.

Engine cooling fan having dynamic unbalance compensation

The invention relates to a cooling fan for a cooling system of the internal combustion engine of a motor vehicle, the cooling fan comprising at least one frame () for retaining a fan motor and a fan motor () for driving a fan wheel (). The invention is characterized in that at least one motor casing component of the fan motor () is injection-molded into the frame material and/or is coated by said material by injection molding when the frame () is formed. The invention also relates to a method for producing said cooling fan. The method according to the invention is characterized in that at least one motor casing of the fan motor () is injection-molded into the frame material and/or is coated by said material by injection molding when the frame () is formed.

Cooling fan and method for producing a cooling fan

The invention relates to a fan, particularly for cooling an internal combustion engine of a vehicle, having an attachment unit, an electric drive motor, and a fan wheel rotating about the fan axis, wherein the attachment unit has a frame, from which bars protrude that cross through an air opening, said bars carrying an attachment element serving to attach the drive motor. The invention proposes that each of the bars () have a cross-sectional contour, wherein at least one cross bar () extending laterally in the direction of the fan axis () is configured between end regions () of the bar () extending in the direction of the fan axis (), defining a bar width (b).

The motor of an automotive cooling fan system is attached to a housing by either bayonet mount, screw mount, or axial-snap features on both motor and housing, as well as a cradle structure on the housing.

Mount for connecting automotive fan motor to housing

A drive unit, in particular for a fan in motor vehicles, is indicated, comprising an electric motor ( ) operated on a DC line (U ), and comprising a device ( ) for controlling the speed of the motor ( ) by changing the operating voltage applied at the motor ( ). In order to cost-effectively realize a stepwise adjustment of the motor speed, the speed control device ( ) comprises a plurality of resistors (R -R ) and a plurality of semiconductor switches (T &mdash;T ) for selectively connecting the motor ( ) in series with at least one of the resistors (R -R )

Drive unit

A novel plug connector is intended to improve the capability of triggering a consumer. The plug connector has a plug which has three contact blades, of which a first contact blade is connected to a first cable connection by means of a first electrical lead element, a second contact blade is connected to a second cable connection by means of a second electrical lead element, and a third contact blade is connected to the second electrical lead element by means of a third electrical lead element and via electric components; one connection cable, leading to the consumer, is soldered to each of the two cable connections. The multi-pole plug connector is especially suitable for electrically connecting an electric controller to an electric motor.
