Abstract
A method for actuating at least one solenoid valve includes detecting a valve actuation signal, energizing the at least one solenoid valve with a specific constant control current for a specific actuation time which follows the detection of the valve actuation signal, and increasing the control current to a full actuation current for a full actuation time which follows the actuation time. The specific constant control current and the actuation time are dimensioned in such a way that at least two different types of solenoid valves can be at least partially opened by the control current during the actuation time.
Claims10
A method for actuating at least two solenoid valves of a valve arrangement, the at least two solenoid valves being different types of solenoid valves that require differing amounts of force to open, comprising:
- detecting a valve actuation signal;
- energizing, for a first actuation time period, the at least two solenoid valves simultaneously with a first constant current in response to detecting the valve actuation signal, a magnitude of the first constant current and a duration of the first actuation time period being configured to at least partially open both of the at least two solenoid valves;
- and
- energizing, for a second actuation time period immediately following the first actuation time period, the at least two solenoid valves simultaneously with a second constant current, a magnitude of the second constant current and a duration of the second actuation time period being configured to completely open both of the at least two solenoid valves, the magnitude of the second constant current being greater than the magnitude of the first constant current.
