A rotating component includes a metal plate fixed to an end portion of the metal shaft, and a resin valve gear integrally formed with the plate by insert molding. The plate is formed with a circular fitting hole that fits with the end portion of the shaft, and a positioning recess that is recessed from one side to the other side of the plate.

A device for limiting or keeping constant a quantity of fluid flowing therethrough, includes: a housing with a front chamber and a rear chamber; a partition arranged in the housing with two or more openings; and a flow limiting element arranged in one or both openings. The flow limiting element includes a housing provided with an inlet, an outlet and a throughflow opening; and a resilient plate-like valve element mounted in the housing, substantially able to close the throughflow opening by resilient movement in the direction of a valve seat arranged in the housing adjacently of the throughflow opening. The valve element is fixed on one side and can move resiliently on the opposite side in the direction of the valve seat. A mould produces one or more injection-moulded products. The injection-moulded product is a flow limiter for limiting the force of the flow of a fluid flowing therethrough.

A control flap (1) has a flap body (2) and a circumferential seal (3) capable of sealing upon abutting to a sealing surface (7) of an opening (8). The flap body (2) and the seal (3) are made of elastomers. The seal (3) is joined to the flap body (2) by a pressure plate (4) made of a thermoplastic. The control flap may be made by a method that includes: producing the flap body (2) from a thermoplastic by injection molding; producing the pressure plate (4) from a thermoplastic by injection molding; producing the seal (3) from an elastomer by injection molding; introducing the pressure plate (4) into the undercut (10) of the seal (3); inserting the pressure plate (4) with the seal (3) into the recess (16) of the flap body (2) and bonding the pressure plate (4) and flap body (2).

The butterfly valve comprises a body in which an inserting space is formed; and a disk inserted into the inserting space of the body, wherein fluid flow is opened or closed in response to rotation of the disk, wherein the disk further includes: a disk body formed of a metal; a first plastic layer formed of a first plastic on the disk body; a second plastic layer formed of a second plastic on the first plastic layer, wherein a melting point of the first plastic layer is different from a melting point of the second plastic layer, and the disk body is formed of a framework structure having an internal space.

A valve arrangement for dispensing a fluid is proposed. The valve arrangement comprises a valve plate for fixing the valve arrangement to a container, a valve housing and a fixing part for fixing the valve housing to the valve plate. The fixing part is welded with the valve plate. Furthermore, a dispensing apparatus with a container and a valve arrangement as well as a production method are proposed.

The present invention discloses a stator assembly with water-isolating sleeve applied to solenoid valve for water and implementation method thereof, the implementation method comprising: forming a coil assembly with a cavity by installing an element including an insert on a coil rack wound with a coil winding; forming a stator assembly by installing an upper magnetic conductive inner sleeve and a lower magnetic conductive inner sleeve at both sides in a holein the coil rack of the coil assembly, and fixing the yoke connecting the upper magnetic conductive inner sleeve and the lower magnetic conductive inner sleeve outside the coil assembly; injecting plastic on the stator assembly to form the stator assembly with water-isolating sleeve.

A component of hydraulics, via which a pressure medium connection or flow can be controlled, includes a first portion which is additively manufactured at least in part and on which there is formed at least one control geometry for controlling the pressure medium connection or flow, and a second portion joined thereto.

Provided is a centrifuge cassette assembly (800) for separating a fluid and related method of manufacture. The cassette assembly includes a first chamber, a second chamber (308), a fluidic channel (808) creating a fluid connection between the first chamber and the second chamber, at least one molded insertion valve (600, 700) configured to control the flow of fluid in the fluidic channel and a heating element (802) for actuating the at least one molded valve. Further provided are Normally Open Valves (NOVs) (700) and Normally Closed Valves (NCVs) (600) which are capable of insertion into, and which control the fluid flow of, the centrifuge cassette assembly.

A solenoid valve includes a housing, a valve element provided in the housing to open and close a valve port, and a resin-molded guide member that includes a support portion supporting the valve element to be slidable in an axial direction, and an attachment portion attached to and in contact with an inner side of the housing. The guide member further includes an intermediate joint portion connecting the attachment portion and the support portion. The attachment portion is larger in shape in an orthogonal direction orthogonal to the axial direction than the intermediate joint portion. The support portion extends in the axial direction from the intermediate joint portion. The guide member has an injection-molding gate mark on an outer face of the attachment portion.
