First Claim
Patent Images
1. A system for a solenoid operated valve, comprising:
- a valve having an inlet and an outlet;
a solenoid coupled with the valve and having a coil;
a controller coupled with the solenoid;
an environmental sensor coupled with the controller;
a power source coupled to the controller; and
a database of predetermined adjustments in power to the solenoid depending on environmental conditions;
wherein the controller is configured to adjust power to the solenoid by one of the predetermined adjustments in power in the database based on input from the environmental sensor; and
wherein the controller is further configured to count a number of operational cycles of the solenoid and the database contains predetermined adjustments in power to the solenoid depending on the number of operational cycles of the solenoid.

Abstract
The present disclosure provides a solenoid valve and associated method of control for compensated performance based on environmental conditions and optionally product life. The solenoid coil power consumption is proactively optimized based on predetermined database information to cross reference a given operating temperature and optionally, valve operating cycles. The net effect is to reduce power consumption under normal conditions and selectively apply higher power to the valve coil when required.

6. A method of controlling a solenoid operated valve having an inlet and an outlet;
- a solenoid coupled with the valve and having a coil;
a controller coupled with the solenoid;
an environmental sensor coupled with the controller;
a power source coupled to the controller; and
a database of predetermined adjustments in power to the solenoid depending on environmental conditions, the method comprising;sensing an environmental condition with the environmental sensor; accessing the database with the environmental condition; determining with the controller whether a power adjustment is to be made based on information in the database for the environmental condition; adjusting the power to the solenoid if the database indicates an adjustment is to be made based on the environmental condition; counting a number of operational cycles of the solenoid; accessing the database with the number of cycles determining with the controller whether a power adjustment is to be made based on information in the database for the number of cycles; and adjusting the power to the solenoid if the database indicates an adjustment is to be made based on the number of cycles. - View Dependent Claims (7, 8, 9)
