Abstract
A valve flow-directing vessel (42) comprising a sleeve (44) having a threaded installation portion (84) for connection to a receiving member, a plunger (46) movable within the sleeve (44) between a closed position and an opened position, and an orifice insert (48/50) fixedly attached to the sleeve (44). The orifice insert (48/50) defines an orifice (132) that is sealed when the plunger (46) is in the closed position and unsealed when the plunger (46) is in the opened position. The orifice (132) is the entrance to a passageway (130) having an exit (134) communicating with a delivery passage of the receiving member, and this exit (134) is positioned beyond the threaded installation portion (84) of the sleeve (44).
Claims23
A flow-directing vessel for installation into an interfacing cavity having a cylindrical wall with a threaded portion, a supply passage located below the threaded portion, and a delivery passage located below the threaded portion;
- the vessel comprising a sleeve, a plunger movable relative to the sleeve, a cup fixedly attached to the sleeve, and a capsule fixedly attached to the cup;
- the sleeve having a threaded portion for mating with the threaded wall of the interfacing cavity to connect the vessel to the interfacing cavity,
- the cup having a U-shape cross-section formed by radially spaced apart inner and outer walls, and an upper axial wall extending between and connecting the inner and outer walls, the upper axial wall including at least one opening, wherein the inner and outer walls and the upper axial wall define a chamber that opens downwardly for communication with the supply passage;
- the capsule comprising an orifice in communication with the at least one opening in the upper axial wall, an exit for communication with the delivery passage, and a passageway from the orifice to the exit;
- the plunger sealing and unsealing the orifice to thereby seal and unseal the passageway from the orifice to the exit such that when the passageway is unsealed, fluid from the supply passage can enter the chamber and pass through the at least one opening in the upper axial wall to the orifice and then through the orifice into the passageway to the exit.
A flow-directing vessel for installation into an interfacing cavity having a cylindrical wall with a threaded portion, a supply passage located below the threaded portion, and a delivery passage located below the threaded portion;
- the vessel comprising a sleeve, a plunger movable relative to the sleeve, a cup fixedly attached to the sleeve, and a capsule fixedly attached to the cup;
- the sleeve having a threaded portion for mating with the threaded wall of the interfacing cavity to connect the vessel to the receiving member,
- the cup having a U-shape cross-section formed by radially spaced apart inner and outer walls and an upper axial wall extending between and connecting the inner and outer walls, the upper axial wall including at least one opening, wherein the inner and outer walls and the upper axial wall define a chamber that opens downwardly for communication with the delivery passage;
- the capsule comprising an orifice for communication with the at least one opening in the upper axial wall, an entrance for communication with the supply passage, and a passageway from the entrance to the orifice;
- the plunger sealing and unsealing the orifice to thereby seal and unseal the passageway from the entrance to the orifice such that when the orifice is unsealed, fluid from the supply passage can enter the passageway through the entrance and pass through the orifice to the at least one opening in the upper axial wall and then into the chamber to the delivery passage.
A flow-directing vessel for installation into an interfacing cavity having a cylindrical wall, a first passage located below the cylindrical wall, and a second passage located below the cylindrical wall;
- the vessel comprising a sleeve, a plunger movable relative to the sleeve, a cup fixedly attached to the sleeve, and a capsule fixedly attached to the cup;
- the sleeve having a mating portion for mating with the cylindrical wall of the interfacing cavity to connect the vessel to the receiving member,
- the cup comprising a U-shape cross-section formed by radially spaced apart inner and outer walls and an upper axial wall extending between and connecting the inner and outer walls, the upper axial wall having at least one opening, wherein the inner and outer walls and the upper axial wall define a chamber that opens downwardly and defines an inlet or outlet for communication with the first passage;
- the capsule comprising an orifice for communication with the at least one opening in the upper axial wall, an exit or entrance for communication with the second passage, and a passageway therebetween;
- the plunger sealing and unsealing the orifice to thereby seal and unseal the passageway between the orifice and exit or entrance such that when the orifice is unsealed the inlet or outlet of the chamber is in communication with the entrance or exit of the capsule through a flow path defined by the chamber, the opening in the upper axial wall, the orifice and the passageway.
