The present invention relates to a multiway valve for controlling at least one flow of at least one fluid, in particular within a motor vehicle, including at least one housing and one valve member disposed at least in areas within at least one valve space which is configured at least in areas within the housing, and by way of changing a rotary position of the valve member within the valve space about a first rotary axis, at least the amount of an inflow of the fluid from at least one first fluid connector into the valve space and/or at least the amount of outflow of the fluid out of the valve space is adjustable by at least one second fluid connector, and the multiway valve includes at least one insert which is disposed at least in areas between the valve member and the housing and is connected in a rotationally fixed manner to the housing.

A throttle valve is provided, including a throttle valve body, a valve plug, a hollow seal, a cover, a spring, and a bushing. A flow path is formed in the throttle valve body. The valve plug is disposed in the throttle valve body. The degree of opening of the flow path is modified by rotating the valve plug. The hollow seal is disposed in the throttle valve body. The hollow seal abuts the valve plug. The cover is connected to the throttle valve body. An outlet is formed on the cover, the cover comprises a cover flange, and the cover flange surrounds the outlet. The spring abuts the cover flange to apply an elastic force to the hollow seal for tightly contacting the hollow seal with the valve plug. The spring is telescoped on the bushing, and a first end of the bushing pushes the hollow seal.

A throttle valve is provided. The throttle valve includes a throttle valve body, a valve plug, a hollow seal and a first scraper. A flow path is formed in the throttle valve body. The valve plug is disposed in the throttle valve body. A notch is formed on the valve plug. By rotating the valve plug, the position of the notch is changed, and the degree of opening of the flow path is modified. The hollow seal is disposed in the throttle valve body. An abutting portion is formed on the hollow seal, and the abutting portion sealably abuts the valve plug. The first scraper is disposed on the valve plug. When the valve plug is rotated, the first scraper abuts the abutting portion to clean the abutting portion.

A valve stem for use in a fluid flow control valve having a valve body configured to receive a portion of the valve stem and to enable the valve stem to selectively rotate within the valve body between a fully-open position, where fluid is permitted to flow through the fluid flow control valve, and a fully-closed position, where fluid is prevented from flowing through the fluid flow control valve. The valve stem includes an elongate valve stem arm having a first end and a second end and a valve stem head integrally formed with and fixedly attached to the second end of the valve stem arm. The valve stem head includes a fluid inlet formed in the valve stem head, and a fluid outlet formed in the valve stem head, and a fluid passage that directs fluid from the fluid inlet, through the valve stem, and out of the fluid outlet.

There is provided an IV flow regulator including a first part integrated with a flow control slit, the flow control slit being along a fluid path; a second part integrated with a central stem, the central stem including a spiral surface configured to contact the flow control slit, an area of contact defined by the spiral surface and the flow control slit being shaped substantially like an orifice to enable flow along the fluid path; and a dead space chamfer included in the second part at a portion of the fluid path subsequent to the area of contact.

A high pressure valve includes a valve body having a surface defining a corresponding portion of a conduit and a pocket. A removable insert is removably inserted into the pocket of the valve body and has surface defining a corresponding portion of the conduit. A seal insert is spaced from the valve body by the removable insert and has an interface with the removable insert. A moving member interfaces with the seal insert for selectively closing the conduit, the interface between the seal insert and the removable insert allows play between the seal insert and the removable insert in response to movement of the moving member.

An angle valve structure includes an angle valve body. The angle valve body is provided with a water inlet channel, a water outlet channel and an accommodation cavity. The accommodation cavity is rotationally provided with a valve core. One end of the valve core exposed outside the accommodation cavity is fixedly connected with a knob. The valve core is provided with a sealing block for sealing the water outlet channel when sealing. The valve core includes a main body part and an elastic arm whose one end is connected with the main body part. One side of the main body part is provided with a mounting slot for placing the sealing block, one side of the elastic arm is provided with an extrusion portion, and the other side of the elastic arm is provided with a contact portion against the sealing block after assembly.

A shoe in form of a slipper or sandal, includes a body 100 adapted to have a first fluid casing 12 and a second fluid casing 14, each having an elastic property, embedded in the front and rear portions of the body, respectively, and an instep strap 120 supported to the body in such a way as to be rotated in a specific section. A rotating shaft 16 is rotated in conjunction with the instep strap, and it includes a first connecting portion connected to the first fluid casing and a second connecting portion connected to the second fluid casing and an internal passage having respective check ball seating portions formed on the inside of the first and the second connecting portions, and with check ball received in the internal passage. When the rotating shaft is inclined by rotation of the rotating shaft, the check ball closely adheres to any one of the check ball seating portions by gravity or buoyancy and regulates a fluid flow to any one of the first and the second connecting portions.

The present invention proposes a balancing valve, a fluid network with such a balancing valve, and a method of maintaining such a balancing valve. The balancing valve comprises a housing having a main fluid passage extending along a main flow axis, a valve body disposed within the housing in the fluid passage, wherein the valve body has a first through hole forming a first fluid passage with a variable first fluid passage cross section. The valve body has a second through hole distinct from the first through hole and forming a second fluid passage in the valve body. The first fluid passage is a main fluid passage and the second fluid passage is a by-pass passage.

A rotary valve has a valve plug that is rotatable in a valve body about a rotational axis. Surface features of the valve plug and surface features of the valve body cooperate to provide a bearing by which the valve plug is rotatably supported with respect to the valve body. In addition, each of the valve plug and the valve body include a plurality of annular projections that encircle the plain bearing and axially overlap one another so as to form a labyrinth that surrounds the bearing. The labyrinth forms a fluid path that collects abrasive particles suspended in the fluid passing through the valve, whereby wear of the valve is reduced.
