  • Electromagnetically actuatable hydraulic proportional valve
    Patent number: 6378545
    Abstract: An electromagnetically actuable proportional hydraulic valve (10) is described, which is distinguished in particular by a constant, low-wear operating performance. This is attained by means of a closing member (60) having an approximately conical sealing body (60c, 70) with a curved dome-like face end oriented toward the valve seat (58). The sealing body (60c, 70) together with the valve seat (58) forms a conical seat valve. The sealing body of the closing member (60) is provided with a flow separation edge (60d), which improves the temperature sensitivity of the proportional valve (10).
