Valve device for a hydraulic circuit and oil pump regulating arrangement

A valve device for a hydraulic circuit, the valve device comprising:

• an actuator unit comprising,
• an electromagnetic circuit comprising an armature configured to move in a translational manner,
• a core,
• a coil carrier,
• a coil configured to be energized, the coil being arranged on the coil carrier, and
• a flux guiding device;
• and
• a valve unit comprising,
• a valve housing comprising a transverse bore configured to serve as a regulating port,
• a regulating slide mounted in the valve housing, the regulating slide being configured to move axially,
• a first outlet port,
• an inlet port,
• a control pressure port arranged between the inlet port and the first outlet port,
• an armature seat,
• a spring element configured to load the armature in a direction out of the actuator unit whereby the inlet port is opened and the armature is moved towards the armature seat,
• wherein,
• the first outlet port is arranged at an end of the valve unit opposite to the actuator unit,
• the regulating port is arranged between the actuator unit and the inlet port,
• a pressure applied to the regulating port acts on the armature in a direction of the actuator unit, and,
• the armature is configured be loadable by the actuator unit and by the pressure at the regulating pressure port via the regulating slide in an opening direction of the first outlet port and of the armature seat.

An oil pump regulating arrangement comprising:

• a valve device comprising,
• an actuator unit comprising,
• an electromagnetic circuit comprising an armature configured to move in a translational manner,
• a core,
• a coil carrier,
• a coil configured to be energized, the coil being arranged on the coil carrier, and
• a flux guiding device, and
• a valve unit comprising,
• a valve housing comprising a transverse bore configured to serve as a regulating pressure port,
• a regulating slide mounted in the valve housing, the regulating slide being configured to move axially,
• an outlet port,
• an inlet port, and
• a control pressure port arranged between the inlet port and the outlet port;
• a variable oil pump comprising,
• a control chamber,
• an oil sump,
• wherein,
• the control pressure port is in a fluid connection with the control chamber,
• the outlet port is in a fluid connection with the oil sump, and
• a discharge pressure of the oil pump is applied to the inlet port;
• an internal combustion engine;
• an oil line configured to branch off at the internal combustion engine;
• and
• other units,
• wherein, the regulating pressure port is connected with the oil line branching off at the internal combustion engine after an oil has flowed through the other units.
