Abstract
A check valve for a spray nozzle including a tubular valve body, a shut-off member and a valve seat, wherein the shut-off member is mounted for movement at least in a longitudinal direction of the tubular valve body. The shut-off member is connected to the valve body by a corrugated tube disposed parallel to the longitudinal direction, wherein the shut-off member is biased toward the valve seat due to the spring effect of the corrugated tube. The check valve is suitable for use in, for example, descaling nozzles.
