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).

A valve assembly includes a body having a fluid inlet disposed on a first end of the body and a fluid outlet disposed on a second end of the body in fluid connection with the fluid inlet. The valve assembly further includes a push-to-connect fitting which is integral to the body and configured to connect to an end of a pipe, a stem configured to seal the body in a first position and configured to allow fluid to flow from the fluid inlet of the body to the fluid outlet in a second position, and a connector surrounding at least part of the push-to-connect fitting. The body is configured to house a sealing ring. The push-to-connect fitting is configured to communicate the fluid inlet with the end of the pipe. The sealing ring secured by the push-to-connect fitting is configured to provide a seal between the fluid inlet and the end of the pipe.

A connector suitable to be connected to a multi port extruded tube comprises a socket suitable for an end section of a multi port extruded tube to inserted into the socket along a linear insertion direction, whereby the socket contains an end section receiving space suitable to receive the end section of a multi port extruded tube, the end section receiving space bordering a first opening suitable for a multi port extruded tube to extend through it, whereby a cap arranged inside the socket such that the cap can slide from a forward position that is closer to the first opening to a backward position that is further away from the first opening, the cap having an outer circumferential surface whereby a sealing is provided inside the socket that contacts the outer circumferential surface of the cap in the forward position of the cap.

A conduit connector and method of construction thereof is provided. The conduit connector includes a body having a through passage extending between open opposite ends and a tubular male port section extending axially to an end face of one of the ends. The tubular male section has an outer surface configured for connection to a tubular conduit and an inner surface bounding at least a portion of the through passage. The end face has an outer annular first surface extending radially inwardly from the outer surface and an inner annular second surface extending radially inwardly from the annular first surface toward the inner surface. The annular second surface forms a counterbore that is recessed axially a first distance from the annular first surface, wherein an annular bead extends from one of the annular second surface or the inner surface, with the entirety of the annular bead remaining recessed below the annular first surface.

An insert piece for inserting into a rapid connector device for fluid lines. The insert piece comprises a hollow cylindrical main part, and the hollow cylindrical main part extends between a front annular surface and a rear annular surface along a cylinder axis and has a passage opening extending along the cylinder axis and an outer lateral surface for arranging on the inner wall of a rapid connector device The passage opening has a passage section which expands in the direction of the front annular surface. The insert piece can prevent a fluid line and/or a rapid connector device from being damaged.

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 present application relates to press fittings. The press fittings may include a connector body and a press sleeve. The connector body includes a connection segment and a retainer segment. The connection segment is configured to receive a conduit. The press sleeve may be crimped on the conduit and the connection segment.

A high-voltage battery component includes a connection device for connecting a coolant line for a coolant to a heat sink of a high-voltage battery. The connection device has a connection part, which is connectable to the heat sink, and a sealing element arranged at the end of the connection part for providing a seal between the connection part and the heat sink. The connection device includes a spreading part, which is movable relative to the connection part. The spreading part, by pushing into the connection part, can be transferred from an insertion position for inserting the connection part into the heat sink into a sealing position. In the sealing position, the spreading part spreads the sealing element radially outward such that the sealing element can be placed in a sealing manner against the heat sink when the connection part is plugged into the heat sink.

A drainpipe coupling is provided to sealably connect an insert pipe with an existing drainpipe. The coupling includes a tubular body positioned concentrically within both the insert and existing drainpipes. A coil spring with an adjustable diameter is positioned around the proximal end of the tubular body, with two actuation ends that move toward and apart from each other, adjusting the spring's diameter. An elastic tubular cover is positioned over both the coil spring and the proximal end of the tubular body, forming a seal at their interface. The coupling features an actuation element within the tubular body, which slides axially to engage the coil spring's actuation ends. The actuation element is connected to a handle that extends through the tubular body and allows axial movement to adjust the diameter. This adjustment deforms the elastic cover, sealing the coupling and ensuring a secure connection between the pipes.
