Abstract

A valve whose valve stroke must be adjusted is provided with a throttle bore. The valve has a guide tube open on the bottom with a press-fit in a valve body through whose through bore the valve closing member of an armature received in a guide tube is accessible for engagement by a scanner pin of a measuring tool. After adjustment of the valve stroke, a throttle insert is introduced into the throttle bore of the valve body, using a double-lipped cuff. While an inner lip seals off the throttle insert in the valve body, an outer lip of the cuff, in cooperation with a housing receives the valve and takes on the function of a check valve. The valve is suitable for anti-lock and/or traction-control systems of motor vehicle brake systems.
