Abstract
A slide valve is described, in particular, for an automatic transmission for motor vehicles. The slide valve includes a valve slide displaceable in a sliding channel and at least two adjacent connecting channels. The sliding channel and the valve slide are configured so that the valve slide in an opened slide position establishes a fluid connection between the two adjacent connecting channels, and the valve slide in the opened slide position is guided in a section of the sliding channel between the adjacent connecting channels.
Claims18
A slide valve, comprising:
- a valve slide which is displaceable in a sliding channel and two adjacent connecting channels;
- wherein the sliding channel and the valve slide are configured so that the valve slide in an opened slide position establishes a fluid connection between the two adjacent connecting channels, and
- wherein the valve slide in the opened slide position is guided in a section of the sliding channel between the adjacent connecting channels;
- wherein an opening section of the valve slide for the opened slide position of the valve slide has a diameter change, which is situated in the longitudinal direction of the valve slide away from a control edge of the opening section;
- and
- wherein the diameter change of the valve slide forms a partial annular surface, which is aligned as to the longitudinal direction of the valve slide, at least one component of a normal vector of the partial annular surface being aligned essentially counter to the arrangement of an actuator for the valve slide.
