The invention provides a citrus juicer (100) comprising: an enclosure (20) defining a cavity (24) for produce for pressing (10) containing a fluid, and an opening for introducing the produce for pressing into the cavity; a cannula (50) for engaging in the produce for pressing, a second portion (54) arranged outside the cavity, and a through opening (58) extending between the first and second portions; an inflatable extensible membrane (80) for compressing the produce for pressing engaged on the first end of the cannula in order to extract the fluid out from the cavity; and an ejector device for discharging the pressed produce.

A system includes a vehicle monument, a hose with a fluid line, and an adapter with a triggering unit and a housing, which has a fluid connection. The fluid connection couples to a fluid mating connection, wherein the monument has a fluid main valve and a control unit for controlling the fluid main valve, an inlet of the fluid main valve couples to a fluid suction source, and a first end of the hose connects to the monument such that a first end of the fluid line is coupled to a first outlet of the fluid main valve. A second end of the hose is connected to the adapter such that a second end of the fluid line is coupled to the fluid connection, and the control unit controls the fluid main valve based on a triggering signal from the triggering unit.

An arrangement for pressing materials containing liquid has mobile press container with an container interior that is divided by a press membrane into a pressure medium chamber and a pressing medium chamber. A filling and emptying opening, which can be closed in a pressure-tight manner, allows material to be pressed to be added to the pressing medium chamber. At least one drainage element is arranged in the pressing medium chamber. An interior of the drainage element communicates with a juice discharge of the press container. A turning device, in which the mobile press container is temporarily received can be rotated during a pressing operation from a filling position, about an angle of less than 360, more particularly of less than 270, in mutually opposing directions of rotation about an axis of rotation. There is also described a method for pressing liquid-containing materials.

A citrus juicer is set forth including a deformable container forming an extracting chamber to receive at least one portion of citrus fruit, and having an opening for introducing the citrus fruit; a frame forming a socket to receive the deformable container; a dividing ridge having a cross-section with a tip oriented towards the extracting chamber, and the dividing ridge being arranged to divide the citrus fruit when the citrus fruit is pressed against the tip thereof; a pressing system to exert pressure on the extracting chamber and against the socket. A method for extracting juice from citrus fruit is also disclosed.
