Definitions
- a disk chamber diaphragm extends into the slot in the position to angularly locate the same, the diaphragm having three edges for respective registry with the top, side, and bottom surfaces of the disk chamber and an arcuate working edge for registry with the exterior surface of the ball shaped bearing portion, the edges in registry with the respective surfaces preventing passage of fluid across the diaphragm within the chamber.
- a resilient member is located at the juncture of the top and side shell surfaces in contact with the diaphragm to simultaneously bias the same toward the ball shaped bearing portion and the bottom chamber surface, and the chamber cap snaps into the shell to bring the bottom surface into fluid sealing contact with the diaphragm thereby forcing the diaphragm against the resilient member.
- FIG. 1 is an elevation partly in section of a register box including the metering assembly of the invention
- FIG. 2 is a section through 2-2 of FIG. 1;
- FIG. 3 is an elevation along 33 of FIG. 2;
- Diaphragm 40 (.062 inch thick) has straight edges 82 and 84 which respectively register with surfaces 44, 48 in grooves 50, 52, and edge 86 running between edges 82 and 84 and registering with rubber insert 56, an arcuate working edge 88 generally opposite edge 84, and a stepped bottom edge 90 where narrow flange 92 terminates at its vertical and horizontal edges 94, 96 respectively at side surface 48 and slightly below annular rim 47 of side portion 46. Ribs 98 run along the sides of diaphragm 40 spaced from and parallel to working edge 88.
- Disk chamber cap 38 provides interior bottom surface 102 of chamber 34, centrally spherically depressed at 104 with relief opening 105.
- the outer periphery of cap 38 is stepped down to provide an annular shelf 106 and a vertical cylindrical rim 108 of diameter substantially equal to the inside diameter of the bottom of shell side portion 46, the cap thus being arranged to be manually snapped into or out of shell 36.
- Disk piston 110 (made of hard rubber) includes a ball shaped bearing portion 112, at the center of conical disk 114, the latter having a full radial slot 116 reduced in width at 118 adjacent the outer edge of the disk.
- Spindle 117 extends from portion 112 along the axis of the conical disk. The diameter of disk 114 and the contour of surface 48 are such that the outer edge of the disk is always fully in contact with surface 48 as it nutates within chamber 34.
- diaphragm 40 is inserted in shell 36 as already indicated, and piston 110 is placed in the shell with the upper part of bearing portion 112 resting in, and spindle 117 extending through, opening 45, and diaphragm 40 in slot 116.
- Working edge 88 of the diaphragm will be in registry with the surface of bearing portion 112.
- Cap 38 is snapped into shell 36 so that the lower part bearing portion 112 is seated in depression 104 and thus supported between surfaces 102 and 44.
- Interior surface 102 comes into tight registry with diaphragm edge 90, with shelf 106 contacting flange 92, forcing the diaphragm slightly upwardly against insert 56.
- a fluid metering assembly comprising:
- said chamber comprising:
- top portion providing a generally conical top interior surface with a central circular opening therethrough and an annular ex tension spaced around said opening and directed upwardly from said top portion, said top portion further including a plurality of vertical lugs spaced along the inside of said extension to strengthen the same, and
- a removable disk chamber cap providing a centrally depressed bottom interior surface generally opposing said top interior surface, said top and bottom interior surfaces supporting said ball shaped bearing portion therebetween at said opening and said depression with said spindle extending through said opening, the outer periphery of said cap being stepped down to provide an annular shelf and a vertical cylindrical rim of diameter substantially equal to the inside diameter of said shell side portion at said annular rim, whereby said cap can be manually snapped into engagement with said shell,
- a disk chamber diaphragm removably received in said grooves to separate said ports through said shell side portion, said diaphragm extending into said slot in said piston to angularly locate the same and having first and second straight edges registering respectively with said top and side interior surfaces in said radial and flat-floored grooves, a third straight edge running between said other two straight edges and registering with said rubber insert in said third groove, an arcuate working edge registering with the surface of said ball shaped bearing portion, and a stepped bottom edge registering with said bottom interior surface when said cap is in said shell, a narrow flange at said bottom edge extending, when said cap is removed from said shell, slightly below said annular rim, and
- said shell having three external vertical bosses contacting said cylindrical wall and supporting said chamber therewithin, one of said bosses having said inlet port through said shell passing therethrough and being grooved to admit an elliptical O-ring, said inlet through said shell being aligned with said inlet through said cylindrical wall, said O-ring providing a seal around said inlets between said chamber and said cylindrical wall to prevent fluid flow from the inlet to the outlet of said housing bypassing said chamber.
