A docking device for mechanically connecting an upper and a lower container module of a multipart container. The docking device includes an upper docking segment which is fastenable on an opening of the upper container module, and a lower docking segment which is fastenable on an opening of the lower container module. Fluid is configured to move from the upper container module into the lower container module. An upper docking region of an upper channel section and/or an upper docking segment and a lower docking region of a lower channel section and/or the lower docking segment can be arranged in such a way that the fluid flows through an externally leak-tight channel in an open valve body position. An actuating assembly is arranged in the upper channel section and/or in the lower channel section.

An air supply device has a simple structure supplying compressed air to pneumatic equipment incorporated into a moving device from outside. The compressed air supply device includes: an air supply head having an opposite surface opposing a connection surface; an air supply rod in the air supply head so as to be capable of reciprocating between a projecting position where a projecting surface protrudes from the opposite surface and a retraction position where the projecting surface retracts from the projecting position; an on-off valve causing a compressed air supply source and an air inflow path to communicate with each other via an air guide path when the connection surface is abutted against the projecting surface; a first magnet on the connection surface; and a second magnet on the opposite surface, and by the magnetic attraction of both first and second magnets, an outlet and an inlet are centered.

A self-sealing hydraulic device has a connecting assembly and a hydraulic assembly. The connecting assembly has an adaptor having a shell, a male fitting, and a barb fitting. The male fitting is mounted in the shell, is axially moveable relative to the shell, and has an axial hole and a radial hole orthogonally communicating with the axial hole. The radial hole is sealed by the shell. The barb fitting is connected to and communicates with both the shell and a hose. The hydraulic assembly is assembleable to the connecting assembly and has a housing, an elastic element, and a valve unit. The housing has a hydraulic chamber and an assembling hole communicating with the hydraulic chamber via a through hole. The elastic element is disposed in the housing. The valve unit is disposed inside the hydraulic chamber and driven by the elastic element to seal the through hole.

A disposable patch pump may be provided with a filling adapter, to ensure filling by an authorized user. The adapter mates with the pump and a source of medicament, such as an insulin vial, to prevent filling the pump directly with a conventional syringe. The adapter and/or pump filling port may be configured with a frangible element, to limit the system to single use.

A probe seal for a female hydraulic coupling member has both internal and external pressure-energized seals. The outer wall or opposing ends of the seal have one or more pressure-energized seals for sealing between the body of the probe seal and the body of a coupling member in which the probe seal is installed. Annular, L-shaped, T-shaped or angled grooves in the inner wall of the seal form cavities and sealing projections that can be urged in an inward, radial direction by fluid pressure within an associated cavity to increase the sealing effectiveness between the body of the seal and the probe of a male hydraulic coupling member inserted in the receiving chamber of the female coupling member.

The invention relates to domestics appliance system which makes use of a push-fit fluid coupling (1) comprising a fluid feeding portion (2) and a fluid receiving portion (3) adapted to cooperate with each other to enable fluid to flow in a downstream direction (D1) from the fluid feeding portion (2) to the fluid receiving portion (3). The fluid receiving portion (3) comprises an actuator (65) comprising a fluid conduit (67) for fluid to flow from the fluid feeding portion (2) to the fluid receiving portion (3). The fluid feeding portion (2) comprises a housing (4) defining a fluid flow path (5) and comprising an opening (6) in which the actuator (65) is intended to be inserted, a chamber (37) arranged in the housing (4) in which fluid is intended to flow, a valve seat (8) and a valve member (7) engaging the valve seat (8) for closing the fluid flow path (5), a first piston (9) slidably received in the chamber (37) downstream of the valve member (7). The fluid feeding portion (2) and the fluid receiving portion (3) are adapted to cooperate with each other such that when the actuator (65) is inserted in the opening (6), the actuator (65) and the opening (6) cooperate with each other to form a fluid seal preventing fluid in chamber (37) to leak out from the chamber (37), then, when the actuator (65) is further inserted in the opening (6), the actuator (65) is adapted to contact the first piston (9) and to displace the first piston (9) in an upstream direction (D2) until the first piston (9) contacts the valve member (7) and lifts the valve member (7) off the valve seat (8) for opening the fluid flow path (5) and allowing fluid to flow in the downstream direction (D1). This invention prevents leak of fluid between the fluid feeding portion (2) and the fluid receiving portion (3).
