Abstract

A flow control module is provided. The flow control module includes a housing as well as an on/off solenoid assembly and a proportional solenoid assembly mounted to the housing. A flow body is situated within the housing and is interposed between the on/off solenoid assembly and the proportional solenoid assembly. The flow body provides for flow management of a flow of fluid through the housing.

First claim

What is claimed is:

1. A flow control module, comprising:
a housing having an inlet and an outlet and a passageway extending between the inlet and the outlet, the passageway defining a flow path through the flow control module;
a first solenoid assembly mounted to the housing, the first solenoid assembly configured as an on/off solenoid assembly such that the first solenoid assembly is operable to allow a flow of fluid along the flow path through the flow control module in an on position and prevent the flow of fluid along the flow path through the flow control module in an off position;
second solenoid assembly mounted to the housing, the second solenoid assembly configured as a proportional solenoid assembly, the second solenoid assembly configured to proportionally control the flow of fluid along the flow path through the flow control module downstream from the first solenoid assembly relative to the flow path through the flow control module;
a flow body having a flow passage therethrough, the flow body situated in the housing along the flow path and interposed between the first solenoid assembly and the second solenoid assembly,
wherein the first solenoid assembly includes a first armature, and wherein the second solenoid assembly includes a second armature and an outer sleeve surrounding the second armature, wherein the second armature includes an annular flow channel formed into an outer surface of the second armature.

2. The flow control module of claim 1 , wherein the first armature including an axially facing seal member, the seal member arranged to sealingly engage a seal surface of the flow body.

3. The flow control module of claim 2 , wherein the seal surface is defined by a ridge having a semi-circular cross section and extending axially away from a flange of the flow body.

4. The flow control module of claim 1 , wherein the flow passage through the flow body has an inlet region and a transition region, wherein the transition region has a variable cross sectional area.

5. The flow control module of claim 4 , wherein the transition region has a maximum diameter of 0.200 inches to 0.350 inches.

6. A flow control module, comprising:
a housing having an inlet and an outlet and a passageway extending between the inlet and the outlet, the passageway defining a flow path through the flow control module;
a first solenoid assembly mounted to the housing, the first solenoid assembly configured as an on/off solenoid assembly such that the first solenoid assembly is operable to allow a flow of fluid along the flow path through the flow control module in an on position and prevent the flow of fluid along the flow path through the flow control module in an off position;
second solenoid assembly mounted to the housing, the second solenoid assembly configured as a proportional solenoid assembly, the second solenoid assembly configured to proportionally control the flow of fluid along the flow path through the flow control module downstream from the first solenoid assembly relative to the flow path through the flow control module;
a flow body having a flow passage therethrough, the flow body situated in the housing along the flow path and interposed between the first solenoid assembly and the second solenoid assembly,
wherein the flow passage through the flow body has an inlet region and a transition region, wherein the transition region has a variable cross sectional area,
wherein the first solenoid assembly includes a first armature, and wherein the second solenoid assembly includes a second armature, wherein the second armature has an internal cavity which has an axially facing opening that faces the transition region of the flow body, wherein a maximum diameter of the internal cavity is equal to the maximum diameter of the transition region.

7. The flow control module of claim 1 , wherein the flow body is removable relative to the housing.

8. The flow control module of claim 1 , wherein the annular flow channel is selectively alignable with a plurality of ports formed through the outer sleeve.

9. A flow control module, comprising:
a housing having an inlet and an outlet and a passageway extending between the inlet and the outlet, the passageway defining a flow path through the flow control module;
a first solenoid assembly mounted to the housing, the first solenoid assembly having a first armature movable relative to the housing;
a second solenoid assembly mounted to the housing, the second solenoid assembly having a second armature movable relative to the housing;
a flow body situated in the housing along the flow path and interposed between the first armature and the second armature, the flow body defining a flow passage through the flow body; and
wherein the flow passage through the flow body includes an inlet region and a transition region, the transition region having a variable cross section,
wherein an annular flow channel is formed in an outer surface of the second armature, the annular flow channel selectively alignable with a plurality of ports formed in an outer sleeve of the second solenoid assembly.

10. The flow control module of claim 9 , wherein the flow body is removable from the housing.

11. The flow control module of claim 9 , wherein the transition region has a maximum diameter of 0.200 inches to 0.350 inches.

12. The flow control module of claim 9 , wherein the first solenoid assembly is configured as an on/off solenoid assembly and the second solenoid assembly is configured as a proportional solenoid assembly, the second solenoid assembly situated downstream from the first solenoid assembly relative to the flow path through the housing.

13. A flow control module, comprising:
a housing having an inlet and an outlet and a passageway extending between the inlet and the outlet, the passageway defining a flow path through the flow control module;
a first solenoid assembly mounted to the housing, the first solenoid assembly having a first armature movable relative to the housing;
a flow body situated in the flow path and having a flow passage therethrough; and
a second solenoid assembly mounted to the housing, the second solenoid assembly having a second armature movable relative to the housing, wherein the second armature includes an internal cavity and a plurality of ports formed through an outer surface of the second armature in communication with the internal cavity, wherein the second armature includes an annular flow channel formed in the outer surface of the second armature, and wherein the second solenoid assembly includes an outer sleeve surrounding the second armature, wherein an annular flow space is defined between an outer surface of the sleeve and an interior surface of the housing, the annular flow ring movable relative to a plurality of ports formed through the sleeve.

14. The flow control module of claim 13 , wherein the flow body is removable.

15. The flow control module of claim 13 , wherein the flow passage through the flow body includes an inlet region and a transition region.

16. The flow control module of claim 15 , wherein the transition region has a maximum diameter of 0.200 inches to 0.350 inches.
