Check valve assembly
First Claim
1. An angled check valve assembly, comprising:
- a pipe housing means having an inlet passageway therein for connection to a fluid supply inlet and an outlet passageway connected to and angled to the inlet passageway to provide an exit outlet which directs fluid from the supply inlet at an angle with respect to its inlet direction;
check valve means, comprising plural checks valve assemblies, each having an outer casing dimensioned to be received in one of the passageways, for preventing reverse flow from the outlet to the inlet;
an installation entry in the pipe housing means to allow for passage of the check valve means into the one passageway of the pipe housing means;
a closure means for fluidly closing and sealing the installation entry;
a spider spacer cage means located between the closure means and the check valve means at a point where the two angled passageways intersect for providing an open passageway for liquid flow from the inlet passageway to be angled to the outlet passageway;
the spider spacer cage means having at least one opening in a side wall thereof aligned with one passageway and a second opening in an end thereof aligned with the outer passageway;
said spacer means being formed as a separate element from the closure means and being rotatable with respect thereto so as to allow the at least one opening to be aligned with said one passageway.

Abstract
An angled check valve assembly having a housing with inlet and outlet passageways angled with respect to each other, and a spider spacer cage at a location which allows flow through the inlet passageway into the spider spacer cage where the flow is then angled and directed through the outlet passageway. One of the passageways has one-way check valve(s) therein to insure one-way flow from the inlet through the outlet passage. An installation entry is provided in the housing for insertion of the check valve(s). The installation entry is sealingly closed by a threaded closure member. The spider spacer cage is rotatable relative to the threaded closure so that, as the closure member is moved inwardly, at least one opening (in the side of spider spacer cage) can be kept in registry with one of the passageways. The spider spacer cage also forces the one-way valve(s) toward an abutment in the housing. The spider spacer cage is indexed to one end of the one-way valve(s), and the valve(s) are indexed to each other and/or the housing, to prevent the closure from moving axially to seal the entry when the one-way valve is inserted upside down so as to prevent flow from the inlet through to the outlet.

13. An angled check valve assembly, comprising:
-
a housing means having an inlet passageway therein for connection to a fluid supply inlet at one angle and an outlet passageway connected to and angled to the inlet passageway to provide an exit outlet which directs fluid from the supply inlet at an angle with respect to its inlet direction; check valve means, comprising plural check valve assemblies, each having an outer casing dimensioned to be received in one of the passageways, for preventing reverse flow from the outlet to the inlet; an installation entry in the housing means to allow for passage of the check valve means into the one passageway of the housing means; closure means for fluidly closing and sealing the installation entry upon axial movement with respect thereto; spider spacer cage means located between the closure means and the check valve means at a point where the two angled passageways intersect for providing an open passageway for liquid flow from the inlet passageway to the outlet passageway; the spider spacer cage means having at least one opening in a side wall thereof to be aligned with one passageway and a second opening in an end thereof to be aligned with the other passageway; wherein the spider spacer cage means moves axially with the closure means when the closure means is axially moved to close off and seal the entry; and index means between respective ends of at least two of the valve means and the spider spacer cage means and the housing means for limiting the movement of the spider spacer cage means and the closure means so as to prevent the closure means from closing off and sealing the entry when one of the valve means is inserted upside down in the one passageway such that it would prevent flow from the inlet passageway through the outlet passageway. - View Dependent Claims (14, 15, 16, 17, 18)

19. An angled check valve assembly comprising:
-
a pipe housing means having an inlet passageway therein for connection to a fluid supply inlet at one angle and an outlet passageway connected to and angled to the inlet passageway to provide an exit outlet which directs fluid from the supply inlet at an angle with respect to its inlet direction; check valve means, comprising plural stacked check valve units, each having an outer casing dimensioned to be received in one of the passageways, for preventing reverse flow from the outlet to the inlet; an installation entry in the pipe conduit means to allow for passage of the check valve means into the pipe housing means; a closure means for fluidly closing and sealing the installation entry upon axial movement with respect thereto; a spider spacer cage means located between the closure means and the plural spaced check valve units at a point where the two angled passageways intersect for providing an open passageway for liquid flow from the inlet passageway to the outlet passageway; the spider spacer cage means having a caged configuration with at least one opening in a side wall thereof aligned with one passageway and a second opening in an end thereof to be aligned with the other passageway; and index means for preventing the closure means for axially moving to closure and seal the installation entry when any one of the plural stack valve units is inserted upside down to prohibit flow from the inlet passageway through the outlet passageway. - View Dependent Claims (20, 21)

22. A check valve assembly, comprising:
-
housing means having an inlet and an outlet, and a passageway connecting the inlet and the outlet; check valve means in said passageway for limiting flow to one direction between the inlet and the outlet, said check valve means comprising plural valve units, each having an outer casing dimensioned to be received in the passageway in a predetermined operational orientation; an installation entry in the housing means to allow passage of the check valve means into said passageway; closure means for closing and sealing the installation entry; and means for preventing the closure means for closing and sealing the installation entry if the check valve means is improperly installed in the passageway in an orientation other than the predetermined operational orientation; wherein said closure means comprises a threaded cap and a spider spacer cage separately formed such that the spider spacer cage is rotatably movable, relative to the threaded cap; and wherein said spider cage has at least one opening in one side thereof and an opening in an end thereof, and wherein said spider spacer cage is positionable within said passageway when the closure means is installed so as to align the opening in the side with the inlet of the housing and the opening in the end with the check valve means. - View Dependent Claims (23)
