Abstract (en)
[origin: EP1270925A2] The valve device has at least two bimetallic plates (52,53) arranged in a housing for temperature-dependent actuation of a control element (51). The control element has an associated second valve seat and the bimetallic plates are arranged between the valve seats (24,25). The device has a feed connection for the overflow quantity, a return connection to the tank and an outlet connection for returning the pressurized medium to the feed side of the injection pump. The connections lead to a housing, whereby their channels open into a housing chamber in which a control element (51) interacts with a valve seat. At least two bimetallic plates (52,53) are arranged in the housing for temperature-dependent actuation of the control element, the control element has an associated second valve seat and the bimetallic plates are arranged between the valve seats (24,25).
