Abstract: A pump assembly includes a housing defining a working chamber, a water pump chamber and a waste pump chamber. A first diaphragm separates the water pump chamber and the working chamber. A second diaphragm separates the waste pump chamber and the working chamber. A common driver member interconnects the first diaphragm and the second diaphragm. Movement of the driven member to a first position creates a positive pressure in the water pump chamber and a negative pressure in the waste pump chamber. Movement of the driven member to a second position creates a negative pressure in the water pump chamber and a positive pressure in the waste pump chamber.

Abstract: A refrigerator storage bin includes a main body portion and a cover. The main body portion defines a bin storage area. The cover selectively provides access to the bin storage area. The cover is pivotally attached to a sidewalk of a cabinet of the refrigerator for rotation about a pivot axis between an opened position and a closed position. The cover and main body portion include cooperating surfaces that articulate to cover from the closed position to the open position in response to translation of the main body portion from a first position to a second position.
Abstract: A retention system for a shelf of a refrigerator includes a retainer member and at least one connector member. The retainer member may extend between the first and second lateral sides of the shelf and may include a central portion positionable above the shelf. The at least one connector member may connect the retainer member to the shelf. The at least one connector member may include a locking mechanism for securing the retainer member at various points along a length of at least one of the lateral sides of the shelf.
Abstract: A reduced water consumption flush toilet for a motor vehicle includes a bowl assembly, a waste ball valve assembly and a water valve assembly. The bowl assembly defines a bowl and a discharge opening at a lower end of the bowl. The waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. The water valve assembly delivers a source of flush water to the bowl. The water valve assembly includes a water valve operable in a water valve open condition and a water valve closed condition. The flush toilet further includes a common actuator for controlling both the waste ball valve assembly and the water valve assembly.

Abstract: A frame for a vehicle opening and associated method of manufacturing. The frame can include straight segments interconnected by corner segments. The method includes forming the straight segments, heating at least end portions the straight segments, and bonding the corner segments between adjacent straight segments.
Abstract: A self-contained sanitary system for a vehicle includes a toilet with a flush tank for storing a source of flush water. The system further includes a spout in fluid communication with the flush tank. The spout has a first open end coupled to the flush tank and a second open end. The spout is coupled for rotation about a generally vertical axis between a stowed position and an access position. The second end is rotatable relative to the first end about a generally horizontal axis between a fill position and a drainage position. The system further includes a bench and a holding tank. The holding tank is removably associated with the toilet and includes a pair of wheels and a retractable handle.

Abstract: A valve assembly may include a valve body having a main body portion and a mounting portion. The main body portion may include a perimeter, a first side and a second side. The first side may define a sealing portion extending proximate to and substantially around the perimeter. The sealing portion may mate with a valve seat. The second side of the main body portion may be convexly curved. The valve body may disposed within a flow path define by one or more conduits. The flow path may have at least a portion with a generally circular cross-section having a radius. The first side may mate with a valve seat. The main body portion may be moveable within the flow path relative to the valve seat between an open position and a closed position.
Abstract: A macerator toilet comprising a toilet body include a bowl portion and a base portion, the base portion defining a chamber and a macerator unit in fluid communication with the bowl portion, the macerator unit completely disposed in the chamber and operative for macerating a waste received from the bowl unit and pump the waste from the macerator toilet.
Abstract: An absorption refrigerator includes a cabinet defining an interior space. The interior space defines a first section, a second section, and a third section. The third section is in fluid communication with the second section and is indirectly cooled by the cool air in the second section. The third section has an operating temperature higher than that of the second section. An internal freezer door is provided inside the cabinet for closing the first section.

Abstract: A latching arrangement for a refrigerator door includes a striker unit, a first latch arm and a second latch arm. The striker unit is secured to a cabinet of the refrigerator. The first latch arm is interconnected to the door for pivotal movement about a generally horizontal axis between a latched position and an unlatched position. In the latched position, the first arm releasably engages a first striker portion of the striker unit. The second latch arm is interconnected to the door for pivotal movement about a generally vertical axis between a latched position and an unlatched position. In the latched position, the second latch arm releasably engages a second striker portion of the striker unit.
Abstract: A refrigerator cabinet includes an interior liner, an exterior cabinet and a breaker assembly. The breaker assembly connects the interior liner and the exterior cabinet and maintains a space therebetween. The breaker assembly includes a first breaker strip. The first breaker strip has a forward leg, a side leg, and a clip portion. The side leg extends from the forward leg and is oriented substantially perpendicular to the forward leg. The clip portion is carried by the forward leg. An adjacent side surface of the exterior cabinet is defined by a sheet of cardboard. The cardboard is captured between the side leg and the clip portion.
Abstract: A flush toilet having two nozzles located within its bowl. The two nozzles being oriented in opposite directions and alternately providing pulses of flush water into and around the bowl.
