Abstract: A galley cart bay door latch system serves to secure catering or galley carts, as are used on commercial aircraft, within the aircraft's galley. The system relies on two substantially horizontally disposed latch levers to secure the galley door which in turn restrains a galley cart in position within the galley. The ends of the latch levers are received in a recess formed in the door to secure the door. Raising the latch lever releases the door and positively pushes the door outwardly. The latching configuration allows the doors to be slammed shut without the need to further manipulate the latch levers.

Abstract: The present disclosure is related, in certain embodiments, to a chilled air distribution system for an aircraft, with a reduced overall foot print and reduced weight, and with an improved overall heat transfer efficiency. The compact lightweight system of certain embodiments is particularly well suited for an aircraft galley that requires refrigerated or cooled carts or trolleys, and/or carts carrying standard meal boxes, and/or chilled food and beverage compartments.

Abstract: A backflow resistant stop valve for an aircraft galley plumbing system comprises a valve body defining an inlet, and inlet chamber, a transfer chamber, an outlet chamber, and an exit. The valve incorporates an anti-backflow device at the exit to prevent backflow, and flow through the body is controlled by a pivoting paddle disposed within the valve body having an upper flap, a spindle, and a lower flap, where the upper flap seals against the inlet chamber and the lower flap seals against the outlet chamber when the paddle is rotated to a first position. The valve utilizes a negative pressure at the outlet chamber that biases the valve closed until a sufficient column of water overcomes the bias.

Abstract: A modular potable water distribution manifold for an aircraft water supply and drainage system includes a tubular element with a first manifold quick connector adapted to mate with a flexible hose connector and having a flow control poppet, a second manifold quick connector having a flow control poppet, the second manifold quick connector adapteded mate with a terminating self-venting/self-draining device, and a rotating ferrule that mates the second manifold with the self-venting/self-draining device.

Abstract: A four-way distribution valve is provided that allows for efficient filling and drainage of a potable water supply and waste system including a potable water distribution manifold and water filter in a commercial aircraft galley. The water distribution valve includes a cruciform manifold having a filter drain port connected to the water filter, two supply manifold ports connected to the potable water distribution manifold, and a drainage discharge port. A rotary closure element within the cruciform manifold actuates in accordance with four selectable filling and discharge modes for the valve to fill and drain potable water in the potable water supply and waste system. As a result, the valve can be used to fill the potable water supply system with potable water before a flight, and to selectively drain potable water from the potable water distribution manifold, the water filter, or both after a flight, all through the same valve.

Abstract: An electrical connection interface system for a galley insert or appliance for an aircraft galley includes a high level interface configured to be electrically connected with an appliance power and control unit or galley power and control unit. In a presently preferred aspect, the galley insert or appliance may be an oven, refrigerator or chiller.

Abstract: A potable water supply and waste system for an aircraft galley is provided that includes a potable water distribution manifold in fluid communication with a potable water source. The potable water distribution manifold is configured to distribute water from the potable water source to a galley insert in a work deck of the aircraft galley. A galley insert drain line is connected to the galley insert for draining waste water from the galley insert into a sump. The sump, in turn, is connected to a main drain line for the potable water supply and waste system that is positioned below the work deck. A rotary, cruciform valve is connected in fluid communication with the potable water distribution manifold and the galley insert. The cruciform valve is selectively configured to allow the potable water source to supply or drain the entire system through the same manifold.

Abstract: An aircraft potable water supply system allows unused water to be recovered for later use. The system prevents cross contamination of potable water, waste water and foul water, drains down the entire system upon aircraft shutdown and refills the system in preparation for a resumption of service.

Abstract: A location and support system for installation of an aircraft galley insert case for location and attachment of an aircraft galley insert in an aircraft galley monument includes a floating stabilizer connector fixedly mounted to an upper surface of the aircraft galley insert case, and a floating receiver shelf engagement insert fixedly mounted to an attachment slot in an upper portion of a compartment in the aircraft galley monument for receiving the aircraft galley insert case. The floating receiver shelf engagement insert includes a slotted portion configured to removably receive the floating stabilizer connector. The aircraft galley insert may also include a plurality of ceramic spacers embedded in formed insulation.

Abstract: A check valve for an aircraft galley plumbing system having a valve body including an inlet for a potable water supply line, and first and second outlet ports leading to a distribution manifold. In a preferred embodiment, quick disconnects that include reverse flow inhibitors seal the valve's output ports. A vertical channel extends through the valve body for draining water through the valve, which is coupled to a pressure line connection port that exerts pressure from the aircraft's pressure system. A piston reciprocating across the vertical channel and biased by a spring is in fluid communication with the pressure line connection port, such that when water pressure is introduced from a pressure line to the connection port of sufficient pressure to collapse said spring, the piston blocks said channel, and when the water pressure is insufficient to collapse said spring then the piston retracts to open said channel.

Abstract: An improved monument structure combining an integrated construction system with carbon fiber reinforced composites to form an exoskeleton chassis that significantly reduces the build times, manufacturing skill level requirements, post processing activities, and overall weight of a given aircraft monument.

Abstract: A rotary latch assembly for a galley cart compartment door is disclosed comprising a barrel member rotating on a spindle and a handle connected to the barrel member. An interfering block outside the barrel member can prevent rotation of the barrel member when engaged with the barrel member, and be displaced by a lock button diametrically opposed with the interfering block. The handle of the rotary latch bears against the door in a locked position to prevent the door from opening, and the button when depressed releases the barrel member to rotate and the handle to pivot out of the path of the door.
