摘要： A double-armature solenoid valve may include an adjustable first armature and an adjustable second armature arranged axially opposite each other along a common adjustment axis, and a coil mechanism configured to provide a magnetic flux. The valve may also include a first restoring spring, a second restoring spring, an inlet opening arranged on an axial side of the first armature opposite the second armature, and an outlet opening arranged on an axial side of the second armature opposite the first armature. The inlet opening and the outlet opening may be connected via a fluid duct. The first armature and the second armature may respectively have a different closing time such that when an energization of the coil mechanism is at least one of interrupted and reduced the inlet opening is closable more quickly via the first armature than the outlet opening via the second armature.

摘要： A cooling circuit arrangement (1) for cooling an engine (2), in particular a motor vehicle combustion engine, by means of a cooling medium, which can be conveyed by a cooling medium pump (4) between a suction side (S) and a pressure side (P) in a cooling medium circuit (3), which comprises a cooler fluid path (7) passing through a cooler (6) and a bypass fluid path (5), wherein a cooling medium valve (8) having an actuator (9) is arranged in the cooling medium circuit (3) for setting a volume flow ratio between cooling medium flows flowing through the cooler fluid path (7) and bypass fluid path (5), wherein the actuator (9) has a hydraulically activatable adjustment element (17), which can be supplied with a cooling medium via at least one control valve (11) allocated to the cooling medium valve (8), in particular from the pressure side (P) out of the cooling medium circuit (3), in order to set the volume flow ratio, and wherein the adjustment element (17) borders a control chamber (19) that can be supplied with cooling medium via the at least one control valve (11), and a valve chamber (20) also supplied with cooling medium, wherein the adjustment element (17) can be displaced in both mutually opposed displacement directions exclusively through exposure to hydraulic pressure by means of the cooling medium, and wherein, in order to displace the adjustment element (11), both the control chamber (19) and valve chamber (20) can be joined with the cooling circuit (3) by means of the at least one control valve (11), or the free flow cross section of corresponding connections can be varied, and that wherein, in order to maintain an adjustment position, the at least one control valve (11) can be used to join both the control chamber (19) and valve chamber (20) with the same cooling circuit side, or the free flow cross section of corresponding connections can be varied, wherein, the at least one control valve (11) has a 4/3-way valve functionality and a pressure-side cooling medium pressure port (P), a cooling medium outflow port (T), a first working port (B) leading to the control chamber (19) and a second working port (A) leading to the valve chamber (20).
