Abstract
A pressure-reducing valve is secured to a proportional magnet by resiliently connecting the valve sleeve of the valve receiving the piston to the housing of the proportional magnet, thus avoiding possible deformations of the valve sleeve resulting from mounting. Furthermore, the operational safety of the valve is improved by abutments limiting the stroke of the valve piston and by a control edge which is additionally provided at the valve sleeve.
