Description

BACKGROUND OF THE INVENTION The invention relates to a fluid transfer body, in particular for transferring liquid media from a conduit to a receiving space, especially a shower © a fluid connection housing, a fluid transfer housing, an annular gap between the flow control body and the liquid transfer housing fixed to the liquid transfer housing, and a closure member preferably fitted with a threaded connection to the liquid transfer housing.

There is a need in many areas of the life of the Liquid Reactor for a fluid to be transferred from one space to another in a controlled manner. A special task is to pass the conveyed medium from the feeder space to the receiving space with precise, web-based control and flow control.

The same applies to shower heads.

In the most commonly used shower jets, water flows through tiny holes or gaps. The disadvantage of the solutions is that, as a result of use, the vitreous deposits are deposited in the small openings and narrowed or completely blocked, thus preventing the function from being properly performed.

In U.S. Patent No. 175,964, water is released along so-called baffle plates that break down the water jet, but the solution only reduces the partial pressure of the water without being able to distribute the discharged water with perfect uniformity.

A more advanced solution is the valve fluid kiosk described in U.S. Patent No. 3,938,743. An adjustable flue valve via a gland is inserted into the water path. The valve is not provided with a suitable diverting valve, so only a quantity can be controlled with it, and proper spreading cannot be achieved.

U.S. Patent No. 3,042,353 discloses a structure in which a non-radial portion of a jet is fed through holes through a ball joint. Its central larger diameter is through a bore into a flowing space in which springs are located.

φ * φφ »«

The purpose of the springs is, on the one hand, to clamp the shower head to the ball joint and, on the other hand, to allow the stopcock set in the path of the jet to move away from the closing plane to a certain value depending on the water pressure. The stop tap - depending on the spring forces - normally closes the water outflow! way. In case of opening the water enters a diffuser, and it directs the water 90 ^ö ~ os íránytoréssei ribbed skirt, which reaches past the water jet in free space and takes an appropriate shape of the rib. up

Although the structure is capable of blocking the path of the outgoing jet, it requires a complicated spring mechanism to control the amount of water exiting. It is also disadvantageous that any dirt (limescale) that gets under the stop tap will obstruct the closing and may obstruct part of the outlet during flow, so that a steady flow of water cannot be guaranteed in the long run.

No. 181,324 has a vortex chamber formed in a shower milk and is provided with a vortex movement device for inflowing liquid. The vortex chamber has an approximately cylindrical shape and is provided with an inlet opening centrally disposed centrally to the central axis of the inflow beam in the downstream direction, and a shower outlet outlet centered along a central axis along the lower front face.

The jet enters the distribution line through a large diameter bore into the distribution space, from where it can exit in two directions, Axially through a larger bore into the vortex space, and laterally, through a vortex wall. As a result of the two flows, a jet of water is pulsating.

While the solution is undoubtedly capable of generating a stream of water from cylindrical rays while performing pulsating, regulatory functions, it is disadvantageous that the laths on the inside of the outlet holes, which are different in the vortex and outlet, are at high risk of leaching.

In the design of patent application HU 199,317, the test jet enters a radially directed, inwardly directed, radial direction through the large diameter sack hole formed from the supply line through the choke body mounted inside the end of the supply line. , leading it to the wall of the valve body, here the water flow is forced to change direction again and enter the vortex space, from where it flows through the annular gap formed between the throttle body, the end of the throttle and the valve to the mouth φφ φφ 1. This solution partially eliminates the shortcomings of the existing solutions, but does not solve the problem of keeping the vf jet constant and correct. One reason for this is that the choke on the end of the power line paints a common unit with the choke, so the receptacle housing - because it can move radially on the rubber ring surface of the choke on the end of the power line ·· between the choke and valve the annular gap formed for the outflow cannot continuously maintain its concentric position and the centralized retention of the fluid flow. As a result, a jet of water is created. Therefore, the jet of water does not perform its function continuously during the shower, so the setting often has to be adjusted by personal intervention,

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fluid flow body that eliminates the disadvantages of the known solutions, enables accurate and infinitely variable volume control, and maintains the precise shape of the effluent stream, even at minimum and maximum VAT flows,

A further objective is to provide an economical fluid inlet paint, robust in the service environment, protected from the weather, from damage and from unauthorized dismantling.

The idea of the invention is based on the recognition that a connecting piece, as an independent unit, must be affixed to the end of the inlet pipe, and the flow control ink must be affixed to the outlet part of the fluid transfer housing.

As a result, the fluid passes through the openings of the flow control body directly into the mixing chamber, whereby the right angles of the surfaces bounding the mixing chamber are selected, mixing the liquid stream and passing through the annular gap open to the annular gap while keeping it.

It is also part of the inventive idea that, in addition to providing a fluid-free flow of fluid, the fluid inlet can be controlled from a control point of view as well, since the fluid transfer body has a suitably slotted flow control body in a fluid transfer housing. installed. The fluid transfer housing with its flow control body mounted therein may move freely and rotate. a sealing member is provided to prevent the fluid transfer housing from sliding off the connection piece in the recess formed in the recess formed on the outer surface of the connection pipe end.

In accordance with the object of the present invention, the fluid transfer body according to the invention, in particular for transferring liquid media from a conduit to a receiving space, in particular for a shower head, has a is provided with a threaded connection to the fluid transfer housing, such that there is a flow through the flow rectifier body and the connection piece, the connection piece being threaded to the end of the inlet pipe, the connection piece having a through opening leads to the flow space, the flow reversing paint is provided with flow passages, the flow passages lead to the mixing chamber, the boundary surfaces of the mixing chamber, the fluid chamber housing has a tapered peripheral surface of the mixing chamber and a deflection surface of the flow guide body, and the peripheral surface of the mouth of the fluid transfer housing is preferably concave.

A further feature of the fluid transfer body of the present invention may be that the flow guide body is integral with the fluid transfer housing.

A further embodiment may be characterized by the fact that the flow guide paint and the facing surfaces of the housing are cylindrical with an annular gap between them.

In one embodiment, there is an elastic sealing ring between the connector and the fluid transfer housing.

In another gifted solution, the fluid transfer housing and the coupling fitting are pivotally mounted.

There are several possible solutions, the connector. mounting aid, eg. has a receptacle for attaching a spiked key.

Χ «« «ν <ψ, * ♦ * ♦

In another embodiment, the connector has an arcuate sheath, an elastic sealing ring between the sheath and the fluid transfer housing, and the contact plane of the fluid transfer housing under the curved shoulder and the contact member of the closure above the connector.

In a further embodiment, the flow-through housing and the closure are rotatable in all directions on the curved periphery of the connector, up to the boundary of the closure.

In a likewise gifted embodiment, the connecting piece and the closing member form a single structural member and are joined to this housing along the mating surface of the closing member.

The greatest advantage of the fluid transfer body of the present invention is that it demonstrably results in a significant amount of fluid flow, which, when used as a shower, results in more than 50% fluid loss compared to conventional, e.g., perforated, metal shower heads. that there was any disruption to the functionality and fun of the experience.

A further advantage is that, by varying the amount of fluid flowing, it allows for a smooth water jacket, hair spray, and strong test stripping of the discharged medium, completed

With the present design, the internal flow conditions are such that the structural portions of the fluid transfer body do not show limescale deposition, but at the same time make it possible to steplessly concentrate between the concentric and the soft liquid jacket and the strong fluid flow.

It is also a significant advantage that the shape of the fluid stream can be precisely controlled and its change can be infinitely variable. The inlet tube is nourishing

By increasing the amount of Φ ΧΦΦΦ ΦΦΚ », we get a closed and continuous fluid coil first. Increasing the flow rate, the lower part of the fluid jacket opens, and a droplet of liquid liquid is created. By further increasing the flow of liquid, while maintaining the cavity shape of the flowable liquid jacket, it gives a more liquid jet to a more powerful outflow.

In our experience, limescale does not really occur. In principle, this occurs only where the flow velocity of the water decreases significantly as pressure conditions change.

It is also advantageous that the liquid-permeable paint can be produced in either a machined or injection molded plastic design. The material is weather resistant.

The invention will now be described in more detail by way of example and drawings;
