Title:
電磁操作される液圧式の比例弁
Document Type and Number:
Japanese Patent JP4658322
Kind Code:
B2
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).
