Air inducer assembly for pressurized flush tank

An air inducer assembly comprising:

• a housing having one or more walls defining a chamber, the housing having a recess in the one or more walls located at a bottom end of the chamber;
• a sealing member received in the recess;
• an outlet located downstream from the chamber and below the recess and the sealing member, wherein the outlet is configured for connection to an inlet of a flush tank;
• a water inlet in communication with the chamber and configured for connection to a water inlet conduit for introducing water into the chamber;
• an air inlet in communication with the chamber and configured to be in communication with a source of air;
• and
• a tube extending into the chamber and toward the outlet, the tube having a distal end located below a top of the recess in the housing, wherein a passage extends from the air inlet through the tube to place the air inlet in communication with the outlet, and wherein the tube is configured to permit air to be drawn from the air inlet through the tube and into the outlet by a flow of the water past the distal end of the tube.

A pressure-assist toilet flush system comprising:

• a tank having an outlet configured for discharging water from the tank and an inlet having a threaded portion;
• a flush cartridge configured for controlling discharge of the water from the outlet of the tank;
• and
• an air inducer assembly connected to the inlet and configured for introducing a mixture of air and the water into the tank, the air inducer assembly comprising:
• a housing having one or more walls defining a chamber;
• an outlet located downstream from the chamber and below a recess and a sealing member, wherein the outlet receives the threaded portion of the inlet of the tank and is connected to the inlet by complementary threading;
• a water inlet in communication with the chamber and configured for connection to a water inlet conduit for introducing water into the chamber;
• an air inlet in communication with the chamber and configured to be in communication with a source of air;
• and
• a tube extending into the chamber and toward the outlet, the tube having a distal end located within the outlet and within the inlet of the tank, wherein a passage extends from the air inlet through the tube to place the air inlet in communication with the outlet, and wherein the tube is configured to permit air to be drawn from the air inlet through the tube and into the inlet of the tank by a flow of the water past the distal end of the tube.
