A leadthrough device holds a conduit in a wall opening of a wall, in particular building wall; and guides the conduit through the wall. The leadthrough device has a holding element with a passage hole, through which the conduit can be led, and has an outer frame. The holding element is resiliently held in the frame interior by at least one spring device.

A gas turbine engine includes a bearing support positioned fore of a compressor section along a primary flowpath. The bearing support internally includes a fluid reservoir with a reservoir tube, a fluid pump with a fluid pump tube, and a fluid coupler coupling the reservoir tube to the fluid pump tube.

A rubber body as an elastic body for closure closes a gap between a partition plate in which a through-hole is formed and refrigeration piping inserted through the through-hole. The rubber body for closure includes a pressurized insertion receiving portion having formed therein an opening into which the refrigeration piping is pressed and inserted, the pressurized insertion receiving portion elastically pressing and contacting in a liquid-tight manner an external surface of the refrigeration piping; a fitting portion fitted in a liquid-tight manner the peripheral edge portion of the through-hole in a state in which an inner circumferential surface of the through-hole is elastically pressed; and a displacement allowance portion that closes a gap between the pressurized insertion receiving portion and the fitting portion, and to allow a relative displacement of the pressurized insertion receiving portion and the fitting portion in a direction parallel to the partition plate.

A device for filling or creating a void within a construction medium. The device has a body having at least one inflatable body portion. Each inflatable body portion has one or more inflatable cavities. There is at least one valve member fluidly connected to the one or more inflatable cavity to control flow of fluid into and inflate said cavity. In-use, the one or more cavities are shaped to substantially fill or create the void in a construction medium when in an inflated state.

An air, acoustic and/or fire sealing device comprising an air, acoustic and/or fire sealing insert body comprising molded foam material, the body having a first end and a second end and a bulk continuous with the first end and the second end; wherein the body has an outer diameter, and the body is adapted to allow one or more pipes, fibers and/or cables to pass through the first and second ends and the bulk; and, a flexible hollow sleeve having an inner diameter, a first open end and a second open end, the ends being axially arranged; wherein the outer diameter of the air, acoustic and/or fire sealing insert body is greater than, equal to, or less than, the inner diameter of the flexible hollow sleeve; and, the air, acoustic and/or fire sealing insert body is arranged in the sleeve, is disclosed.

An arrangement for use in adjoining a support structure to a pipe that passes through the support structure. The arrangement comprises a mount attachable to the support structure. Radial bellows are connected to the mount. The bellows are arranged in use to extend circumferentially around a pipe and be connectable thereto such that a volume is defined by the bellows, mount and pipe.

A leadthrough device holds a conduit in a wall opening of a wall, in particular building wall; and guides the conduit through the wall. The leadthrough device has a holding element with a passage hole, through which the conduit can be led, and has an outer frame. The holding element is resiliently held in the frame interior by at least one spring device.

The invention relates to a line feed-through (1) for feeding a line (4) through a building component, comprising one or more sealing arrangements (2) for feeding the line (4) through, wherein the one or more sealing arrangements (2) have at least two sealing structures (51) lying opposite each other, wherein at least one first of the sealing structures (51) has an arrangement of elongate fins (53) adjacent to each other, the protruding ends of which lie against a second of the sealing structures (51) and thus seal the passage region.

An interface system for mechanically decoupling a cooling system includes: a housing having an opening; an inset having opposite first and second sides; an interface body having first and second ends and a bore-hole open to the first and second ends thereof. The inset has a recess in the second side to accommodate the interface body. The interface body is at least partially inserted into the inset, and the inset is at least partially inserted into the opening in the housing such that the first side of the inset is inside the housing. The first side of the inset has an opening open to the bore-hole of the interface body. One end of the bore-hole is configured to slidably receive an inlet of a cooling pipe, and the other end of the bore-hole is configured to be connected, in a fluid-tight manner, with an external coolant supply or coolant discharge.

A sealing system including a first end and a second end with flexible bellows extending therebetween. The first end includes a base plate with an inner ring having an inner diameter. The inner ring is configured to receive a pipe therethrough. The pipe has an outer diameter, which is smaller than the inner diameter of the inner ring. The bellows of the sealing system has a first length in a first position and second length in a second position. Upon axial expansion of the pipe, the bellows is configured to move from the first position to the second position. The sealing system may also comprise a mechanical protective element, such as a shroud which extends around the bellows. Movement of the bellows can be further limited with rods extending from the shroud to a surrounding substrate or a cable fixing a maximum distance between the pipe and the shroud.
