A flow-control valve has a housing, a guide fixed in the housing and having a tubular end and formed with a radially throughgoing heart-shaped valve opening, and a slide axially shiftable in the housing and having a shaft and a sleeve extending axially from the shaft and snugly surrounding and slidable on the guide-body end. The slide is axially shiftable between positions with the sleeve completely blocking, partially blocking, and completely unblocking the valve opening. An electromagnetic linear actuator in the housing can axially shift the slide. A support ring fixed to the actuator and to the guide forms with the guide-body end an annular chamber into which the valve opening opens and is formed with a radially throughgoing port opening into the chamber and radially aligned with the valve opening. |
