Abstract
A solenoid pump, including: an inlet port, an outlet port, and a first through-bore connecting the inlet and outlet ports; a plunger disposed within the first through-bore and including a second through-bore; a spring arranged to urge the plunger toward the outlet port; a solenoid coil disposed about a portion of the plunger and arranged to displace the plunger toward the inlet port in response to coil power applied to the solenoid coil; and a control unit for: accepting an input voltage; generating the coil power during an interval equal to a first time period; supplying the coil power to the solenoid coil; and selecting a duration of the first time period such that the duration of the first time period varies according to the input voltage.
Claims7
A solenoid pump, comprising:
- an inlet port, an outlet port, and a first through-bore connecting the inlet and outlet ports;
- a plunger disposed within the first through-bore and including a second through-bore;
- a spring arranged to urge the plunger toward the outlet port;
- a solenoid coil disposed about a portion of the plunger and arranged to displace the plunger toward the inlet port in response to direct current coil power applied to the solenoid coil;
- and,
- a control unit including:
- an input for accepting a direct current input voltage;
- and,
- a power circuit for:
- receiving the direct current input voltage;
- generating the direct current coil power during an interval equal to a first time period;
- supplying the direct current coil power to the solenoid coil;
- and,
- selecting a duration of the first time period such that the duration of the first time period varies according to the direct current input voltage, wherein the control unit is for:
- comparing the direct current input voltage to a pre-determined value;
- and,
- selecting the duration of the first time period according to a difference between the direct current input voltage and the pre-determined value.
The solenoid pump of claim wherein:
- the control unit includes a voltage storage element;
- and,
- the control unit is for:
- charging the voltage storage element with the direct current input voltage to generate the direct current coil power during the interval;
- and,
- discharging the voltage storage element to supply the direct current coil power to the solenoid coil.
