A toilet fixture is provided including an inlet pipe, a toilet bowl in fluid communication with the inlet pipe, an outlet pipe in fluid communication with the toilet bowl, a jet pipe in fluid communication with the inlet pipe and the outlet pipe, and a removable jet pipe assembly that connects the jet pipe to the outlet pipe. A foreign object strainer may be positioned in-line with the inlet pipe. A flush assembly may also include a flush valve, a vacuum breaker tube in fluid communication with the flush valve, a foreign object strainer in fluid communication with the vacuum breaker tube, and an outlet pipe in fluid communication with the foreign object strainer.

A tankless toilet includes a bowl, a trapway, and a jet. The bowl includes a rim at an upper portion of the bowl and a sump at a lower portion of the bowl. The trapway extends from the sump to a drain. The jet includes a main channel configured to receive a supply of water from a supply conduit, and a plurality of distribution channels configured to introduce water received from the main channel to at least one of the sump and the trapway. The jet is configured to receive the supply of water from the supply conduit at a first flow rate and induce a flow from the supply of water into the trapway at a second flow rate greater than the first flow rate to prime a siphon within the trapway. The second flow rate is greater than the first flow rate prior to priming the siphon.

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

The invention relates to a tankless intelligent toilet, using a direct flush technique, comprising a hinged pan (5), a bowl (2) with a water seal against odours (21), a funnel (3) below the bowl (2), for removing waste and a control unit (8) operationally connected to: a presence sensor (19); a flow sensor (12), which measures the amount of water flowing into the system; a solenoid valve (13), which allows or prevents the inflow of water into the toiler; an actuation mechanism (16), which opens and closes the hinged pan (5); and a locking mechanism (9) which locks the hinged pan (5) in the closed position. The flush mode of the toiler can be determined and the water supply to the system can be controlled, maintaining the water seal against odours, ensuring low water consumption with each flush, independently of the supply pressure, and guaranteeing a high level of performance.

A soil densification system and method is disclosed. The presently disclosed soil densification system includes an air delivery probe or pipe that can be driven or otherwise installed into a soil mass. An inlet of the air delivery probe is supplied by an air compressor and an air storage tank, which are used for the rapid delivery of air impulses or bursts into the air delivery probe, whereas the air impulses or bursts are expelled out of an outlet of the air delivery probe and into the soil mass. The method of using the presently disclosed soil densification system includes the steps of inserting the end of the air delivery probe into the soil mass to any desired depth and then releasing an impulse or burst of air into the soil mass, thereby forming a densified region in the soil mass via the forces of the air impulse.

Sanitary-ware coupled to a mains water supply, the sanitary-ware including a flushing assembly including a tank having a first chamber having a first volume and an inlet, and a second chamber having an outlet and a second volume, larger than the volume of the first chamber; the inlet coupled to a source of water at high pressure receiving a first quantity of water at an inlet pressure from the source; and a pressure exchange mechanism disposed between the first chamber and the second chamber, wherein a first quantity of water in the first chamber causes a second quantity of water in the second chamber, larger than the first quantity, to be pushed out of the second chamber through the outlet at a pressure lower than the inlet pressure by the pressure exchange mechanism. Preferably, the source of water at high pressure is a mains water supply.
