PCT No. PCT/DK93/00266 Sec. 371 Date Feb. 3, 1995 Sec. 102(e) Date Feb. 3, 1995 PCT Filed Aug. 16, 1993 PCT Pub. No. WO94/05937 PCT Pub. Date Mar. 17, 1994A valve with presetting facility has a valve housing with a rotatable sleeve. To form a present throttle, a control opening at the base of the sleeve co-operates with a control opening at a base face of the valve housing. The control opening in the base face is formed by an eccentric bore. The control opening in the end face of the base is formed by a channel which extends over a circular arc of less than 360 DEG , is connected at one end by way of an eccentric bore to the inner space of the sleeve and has a cross section that reduces towards the other end. That allows presetting to be very precise and manufacture to be inexpensive.
