Description

[0001] A FLUID TRANSMISSION MECHANISM

[0002] The present invention relates to a fluid transmission mechanism that prevents the pipe that transmits fluid to the mobile equipment from being affected by external factors during movement.

[0003] The fluids like cooling gas and cooling liquid transmitted to the equipment carried on a mobile structure must be transmitted to the equipment without interruption. Some of these equipment, which can be avionic equipment in aircraft, are cooled by forced cooling. This method is carried out by transmitting the cooling fluid into the equipment through a pipe positioned on the equipment. If the pipe that carries the cooling fluid into the equipment is affected by external and / or internal factors, the equipment may fail to provide operating conditions and a malfunction may occur.

[0004] In the Korean patent document numbered KR101949135B1 in the state of the art, a structure developed to support a ventilation drainage hose horizontally from one end is described. There is an extended unit at the other end of the hose. There is a section shape suitable for the outer diameter of the hose and the extended section and a hose support on the upper surface of the table. This system provides the ability to reduce the shock caused by internal or external factors occurring in the processing device during the processing of automotive air conditioning hoses and to realise stable operations.

[0005] The Korean patent document numbered KR20070081208A in the state of the art describes a gasket used to support the vehicle air conditioning drain hose. The gasket is fixed in a hole formed in the vehicle body cover and has an elastic reinforcement and a large diameter protrusion. This protrusion is tightly located in the hole and is in contact with the body cover. By means of a fluid transmission mechanism developed with the present invention, the air conditioning pipes mounted on the movable cover and carried to the equipment requiring cooling are prevented from bending during the cover movement.

[0006] Another aim of the invention is to ensure a more compact equipment placement and to facilitate access to the equipment.

[0007] Another aim of the invention is to provide the routing of the cooling pipes that transmit fluid to the equipment mounted on the movable cover.

[0008] Another aim of the invention is to ensure that the cover is opened and closed in cases where access is required for maintenance and repair purposes inside the covers on which equipment is located in aircraft without the need to stop the operation of the equipment located on the cover.

[0009] The fluid transmission mechanism defined in the first claim and the claims dependent on this claim, which is realised to achieve the aim of the invention, comprises a body that can be an aircraft. There is equipment mounted movably on the body. The equipment performs the aircraft functions previously determined by the user. There is a first position (I) in which the equipment is positioned on the body in a manner determined by the user. The equipment is moved away from the body while in the first position (I) and brought to a second position. There is at least one pipe between the body and the equipment that carries fluid to the equipment from inside or outside the body.

[0010] Said fluid transmission mechanism comprises a support element that is located outside the pipe that is positioned between the body and the equipment along its length and surrounds a part or all of the pipe. The support element prevents the twisting of the part surrounded by the pipe moving between the first position (I) and the second position (II) and allows the flow rate of the fluid carried in the pipe to be kept within the range determined by the user.

[0011] In one embodiment of the invention, the transmission mechanism comprises an opening between the pipe and the equipment with a size that is determined by the user or manufacturer, and allows the pipe to shorten a little and come to the first position (I) where it approaches the inner wall of the support element and extends a little and comes to the second position (II) away from the inner wall of the support element.

[0012] In one embodiment of the invention, the fluid transmission mechanism comprises at least two stoppers, one positioned between the support element and the equipment and the other positioned between the body and the support element. The stopper prevents the support element from twisting by coming into direct contact with the equipment when the equipment is in the first position (I). The other stopper ensures that the pipe remains fixed linearly in a way that is limited to a length in line with the length of the support element when it is in the first position (I). The stoppers remain opposite each other in the first position (I).

[0013] In one embodiment of the invention, the fluid transmission mechanism comprises a swivel connector that is fixed to the body at one end and attached to the pipe at the other end, and allows the pipe to move with the equipment during the movement of the equipment between the first position (I) and the second position (II) by making a free rotation movement with the end where it is attached to the pipe as a rotation point.

[0014] In one embodiment of the invention, the fluid transmission mechanism comprises a connector spacer that provides the connection between the swivel connector and the pipe, which is produced in a way that one end of which is compatible with a swivel connector and the other end with the pipe.

[0015] In one embodiment of the invention, the fluid transmission mechanism comprises a cover that is positioned movably on the body and has equipment placed on at least one surface in a removable manner.

[0016] In one embodiment of the invention, the fluid transmission mechanism comprises a helical spring that is positioned to extend lengthwise inside the pipe, allowing the pipe to lengthen and shorten somewhat during the movement of the equipment between the first position (I) and the second position (II) and allowing the inner wall of the pipe to remain at an almost constant diameter.

[0017] In one embodiment of the invention, the fluid transmission mechanism comprises a support element that is located outside and almost in the middle of the pipe, on the outer wall of the pipe, and thereby prevents the pipe from hitting the equipment and / or the body and getting damaged while the equipment is moving between the first position (I) and the second position (II).

[0018] In one embodiment of the invention, the fluid transmission mechanism comprises two stoppers, at least one of which is located between the equipment and the pipe, and the other between the connector spacer and the pipe. The stopper between the equipment and the pipe provides the equipment-pipe connection, while the stopper between the connector spacer and the pipe provides the connector spacer and the pipe connection.

[0019] In one embodiment of the invention, the fluid transmission mechanism comprises a clamp in the form of a girth gear, which is located on the stopper and wraps around the pipe from the outside and allows it to be attached to the stopper.

[0020] In one embodiment of the invention, the fluid transmission mechanism comprises a screw in the form of a girth gear, which allows the clamp to be tightened and loosened by the user to the desired amount, on the stopper that holds the clamp.

[0021] In one embodiment of the invention, the fluid transmission mechanism comprises at least two walls that are opposite each other at both ends of the support element and extend outward from the outer wall of the support element. It comprises two gaskets, each positioned on a wall and having a slightly flexible structure, and prevent direct contact and create a slight damping effect by remaining between the support element and the stopper when the cover is in the first position (I) or second position (II). The gaskets prevent damage to the support element in the event of sudden opening or closing of the cover. In one embodiment of the invention, the fluid transmission mechanism comprises a cover holder, one end of which is connected to the body and the other end to the cover, and allows the cover to come from the first position (I) to the second position (II) and to be kept fixed in the second position (II) by opening for a predetermined distance.

[0022] In one embodiment of the invention, the fluid transmission mechanism comprises a body that is an aircraft such as an airplane or helicopter. There is a cover that is located on the body and allows the user to access the inside of the body. The equipment is positioned on the cover. The flow rate of the fluid transmitted to the equipment through the pipe is protected by the support element in the first position (I) and second position (II).

[0023] In one embodiment of the invention, the fluid transmission mechanism comprises an equipment that can be avionics equipment that operates within a temperature range predetermined by the manufacturer and into which coolant is sent through a pipe.

[0024] The fluid transmission mechanism realised to achieve the aim of this invention is shown in the attached figures, and of these figures;

By means of the support element (5), the pipe (4) is prevented from being damaged by bending as it moves between the first position (I) and the second position (II) and / or the flow of the fluid carried in the pipe (4) is prevented from being interrupted.

[0054] In one embodiment of the invention, the fluid transmission system (1) comprises an opening that allows the pipe to at least partially shorten and approach the wall of the support element (5) to reach the first position (I) and allows the pipe to at least partially extend and move away from the wall of the support element (5) to reach the second position (II) and allows a distance predetermined by the manufacturer to remain between the pipe (4) and the equipment (3). By means of the opening, the pipe (4) is almost completely inserted into the support element (5) when it is in the first position (II).
