Abstract (en)

[origin: EP2241763A2] The device (H) has a pressure switch (W) designed as a 2/2-way seat valve (14) with a valve member forming a control member and a valve seat arranged in a discharge path (13). A pressure source (P) is permanently connected with a valve assembly (V) via a restrictor (D). The discharge path branches between the restrictor and the valve assembly to a reservoir (R). Control pressure subjected to the valve member in switching direction toward the valve seat is derived from supply pressure between the pressure source and the restrictor.
