HllS ATTORNEYS 1 VALVE CONSTRUCTION This invention relates to an improved valve construction as well as to improved parts for such a valve con struction or the like.

It is well known that various valve constructions have been provided wherein the movable valve member is controlled by a solenoid plunger or the like moved between its various positions by an electrical coil means.

It is a feature of this invention to provide an improved valve construction of the above type wherein an ease of assembly is provided by utilizing a minimum number of uniquely formed parts.

Another feature of this invention is to provide such a valve construction wherein a sealed armature and valve assembly is obtained without the necessity of soldering or brazing.

A further feature of this invention is the use of a pole piece and shading ring assembly that can be snapped into the housing means of the valve construction and still maintain sufficient flux density for good armature action.

Another feature of this invention is to provide a valve construction wherein the various parts thereof eliminate the need for adjustment necessary to maintain proper valve closure when the armature is in a deactuated or seated position thereof.

A further feature of this invention is to provide a valve construction wherein field repairs can be easily made and different voltage coils can be installed in the field.

In particular, one embodiment of this invention pro- 1 vides a housing means having a valve seat and a valve member for opening and closing the valve seat. A lever is pivotally carried by the housing means and carries the valve member whereby pivoting movement of the lever moves the valve member relative to the valve seat for controlling the valve seat. A movable actuator member is carried by the housing means and is interconnected to the lever by a leaf spring so that movement of the actuator member is transmitted by the leaf spring to the lever to pivot the lever and thereby move the valve member relative to the valve seat whereby the leaf spring eliminates the need for making adjustments to insure proper valve seating.

Accordingly, it is an object of this invention to provide an improved valve construction having one or more of the novel features set forth above or hereinafter shown or described.

Other objects, uses and advantages of this invention are apparent from a reading of this description which proceeds with reference to the accompanying drawings wherein:

FIG. 1 is a perspective view of the improved valve construction of this invention.

FIG. 2 is an enlarged cross-sectional view taken on line 2-2 of FIG. 1.

FIG. 7 is a perspective view of one of the parts of the valve construction of FIG. 2 with. FIG. 7 being reduced in size.

FIG. 8 is an exploded perspective view of various parts of the valve construction of FIG. 2.

While the various features of this invention are hereinafter described and illustrated as being particularly adapted to provide a valve construction to be solenoid operated, it is to be understood that the various features of this invention can be utilized singly or in any combination thereof to provide other types of valve constructions as desired.

Therefore, this invention is not be limited to only the embodiments illustrated in the drawings, because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention.

Referring now to FIGS. 1 and 2, the improved valve construction of this invention is generally indicated by the reference numeral 10 and comprises a housing means 11 formed from a first housing part 12 carrying a cover member 13 and being secured to a second housing part 14 by threaded fastening members 15 to define a sealed chamber 16 therebetween.

The first housing part 12 is formed from plastic material suitably molded or otherwise formed to define a substantially fiat plate-like part 17 and an outwardly extending closed ended tubular part 18 having its upper end in FIG. 2 completely closed by an end wall means 19 while its lower end 20 leads to the chamber 16 when the housing members 12 and 14 are secured together in the assembled relation illustrated in FIG. 2. a

The other housing member 14 is also formed from plastic material suitably molded or otherwise formed into a substantially cup-shape and thereby defines a closed end 21 and an open end 22, the open end 22 having an annular groove 23 formed therein and being adapted to telescopically receive an annular flange 24 projecting outwardly from the plate part 17 of the housing member 12 as illustrated in FIG. 2 to trap and hold an annular sealing member 25 therebetween whereby the housing members 12 and 14 cooperate together to define the sealed chamber 16 therebetween when the same are secured together by the fastening members 15.

The closed end 21 of the housing member 14 is provided with three nipple extensions 26, 27 and 28 extending in opposite directions from the end wall 21 with the upper ends 29 and 30 of the nipple extensions 26 and 28 defining valve seats having passage means 31 and 32 passing therethrough.

The middle nipple extension 27 has an upper end 33 disposed lower than the valve seats 29 and 30 and has a passage means 34 passing therethrough whereby a suitable pneumatic pressure source 35 is adapted to be coupled to the nipple extension 27 by suitable conduit means 36 and, thus, be interconnected to the chamber 16 of the valve construction 10. The nipple extensions 26 and 28 can be respectively interconnected to pneumatically operated devices 37 and 38 by suitable conduit means 39 and 40 whereby the pneumatic pressure source 35 is adapted to be interconnected to the pneumatically operated device 37 or to the pneumatically nular groove 43 provided in a surface 44 thereof has an.

annular groove 45 formed in the outer cylindrical sur face 46 thereof and is adapted to snap-fittingly receive an inwardly directed annular tongue 48 formed on the internal cylindrical surface 49 of the tubular part 18 of the housing member 12 whereby the pole piece 41 and its shading ring 42 are adapted to be snap-fitted in the upper end of the tubular part 18 so as to provide sufficient flux density for good armature action as will be apparent hereinafter.

An electrical coil 50 is adapted to have its insulating carrier or bobbin 51 telescopically disposed about the tubular part 18 of the housing member 17 and be secured in place by a frame structure 52 being held on the housing member 12 by the same fastening member 53 that fastens the cover member 13 to the tubular part 18 of the housing member 12, the fastening member 53 being threaded into a threaded bore 54 at the upperend 55 of the tubular part 18. Suitable upper and lower core inserts 56 and 57 are utilized between the coil bobbin 51 and the tubular part 18 of the housing member 12 as illustrated in FIGS. 2 and 7.

A cylindrical armature or actuator member 58 is disposed in the tubular part 18 of the housing member 12 and has an annular groove 59formed adjacent the lower end 60 thereof, the lower end 60 of the armature or plunger 58 normally resting on an annular flange 61 projecting upwardly from the bottom wall 21 of the housing member 14 when the coil 50 is in a deenergized condition thereof. However, the armature 58 is pulled upwardly against the pole piece 41 when the coil 50 is energized in the manner illustrated in FIG. 4 whereby FIG. 2 illustrates the armature 58 in its deactuated or seated position and FIG. 4 illustrates the armature 58 in its actuated position.

A lever member 62 is pivotally carried in the chamber 16 of the valve construction by a pivot pin 63 passing through suitable openings 64 in the lever 62 and having its opposed ends 65 and 66 respectively received in notches 67 and 68 formed in flat upper surfaces 69 and 70 of a pair of embossments or ears '71 and 72 formed integral with the side wall means 93 of the housing member 14. The ends 65 and 66 of the pivot rod 63 are respectively held in place within the grooves 67 and 68 by washers 73 and 74 being secured on the flat upper surfaces 69 and 70 of the ears 71 and 72 by threaded fastening members 75 and 76 as illustrated in FIGS. 2 and 4.

The lever 62 carries a pair of resilient valve members 77 and 78 snap-fitted thereto at the opposed ends 79 and 80 of the lever 62 with such resilient valve members 77 and 78 being adapted to respectively cooperate with the valve seats 29 and 30 for controlling the same.

In order to translate axial movement of the armature 58 to pivotal movement of the lever 62;, as well as to eliminate any need for adjustment between the armature 58 in its seated or deactuated position and the pivoted position of the lever means 62 for normally maintaining the valve member 77 in its closed position against the valve seat 29, a leaf spring 81 is also pivotally mounted to the pivot pin 63 at a central portion 82 of the leaf spring 81 with the leaf spring 81 having one free end 83 disposed adjacent the end of the lever 62 and the other end 84 thereof being bifurcated and suitably formed to receive the reduced portion 95 of the armature 58 at the annular groove 59 thereof therebetween in the manner illustrated in FIGS. 2 and 4.

A compression spring 85 is disposed about the upper part of the nipple extension 28 of the housing member 14 so that the lower end 86 of the spring 85 bears against the end wall 21 of the housing member 14 and the upper end 87 thereof bears against the end 80 of the lever 62 to normally tend to maintain the same in the pivoted position illustrated in FIG. 2 where the valve member 77 is closing the'valve seat 29 and the valve member 78 is in an open position relative to its valve seat 30. In addition, with the armature 58 in its deactuated or seated position, the upper annular shoulder 88 thereof bears against the end 84 of the leaf spring 81 and causes the same to engage against the end 79 of the lever 62 and hold the same in a downward position with the valve member 77 disposed against the valve seat 29 to fully close off the valve seat 29 from the chamber 16.

The operation of the valve construction 10 will now be described.

When the coil 50 is in its deenergized condition, the weight of the armature 58 causes the same to have the end 60 thereof seated against the annular flange 61 of the housing member 14 whereby the valve member 77 is held firmly against the valve seat 29 to prevent fluid communication between the chamber 16 and the pneumatically operated device 37 in the manner illustrated in FIG. 2. However, such pivotal position of the lever 62 causes the valve member 78 to be in an open position relative to the valve seat 30 so that the pressure source 35 is interconnected to the pneumatically operated device 38. The valve member 77 is assured of being maintained against the valve seat 29 because the leaf spring 81 can bend in opposition to its natural bias relative to the lever 62 even though the leaf spring 81 is engaging against the lever 62' when the lever 62 is maintaining the valve member 77 against the valve seat 29 whereby no adjustments are needed between the armature 58 and the valve lever 62 to assure that the valve member 77 will be in its seated position against the valve seat 29 when the armature 58 is in its seated position against the valve member 14. Further, the compression spring 85 also tends to maintain the lever 62 in its valve seating position on the valve seat 29 should the leaf spring 81 not engage against the lever 62 when the armature 58 is seated against the flange 61.

When the coil 50 is energized and remains energized, the same pulls the armature 58 upwardly to the actuated position illustrated in FIG. 4 wherebythe lower annular shoulder 89 of the armature 58 pulls the end 84 of the lever 81 upwardly to pivot the same in a clockwise direction from the position illustrated in FIG. 2 to the position illustrated in FIG. 4 where the end 83 of the leaf spring 81 engages against the valve member 78 and moves the same downwardly in opposition to the force of the compression spring 85 whereby the lever 62 is pivoted in clockwise direction so that the valve member 78 now closes off the valve seat 30 as illustrated in FIG. 4 while the valve member 77 is moved away from the valve seat 29. In this manner, the valve lever 62 now interconnects the pneumatically operated device 37 to the source 35 while disconnecting the pneumatically operated device 38 from the source 35.

Thus, because of the flexibility of the leaf spring 81 between the armature 58 and the valve lever 62, regardless of the seated or actuated position of the armature 58, the lever 62 is sufliciently pivoted so that the same will open one valve seat while closing the other valve seat in the manner previously described. Accordingly, no adjustments need be made between the armature 58 and the valve member 62 in order to assure that proper valve seating will be provided by the valve construction of this invention.

- Further, it can be seen that the various parts of the valve construction 10 of this invention are uniquely formed so that the same can be relatively easily assembled together without requiring soldering or brazing while the chamber 16 is completely sealed closed from the exterior of the housing means 1 1 except for the nipple extensions 26, 27 and 28 thereof because the pole piece 41 and its associated shading ring 42 can be snapfitted in place in the tubular part 18 of the housing member 12 in a simple and effective manner.

Therefore, it can be seen that not only does this invention provide an improved solenoid operated valve construction, but also this invention provides improved parts for such a valve construction or the like.
