A ventilation device has a frame (12) made of a first material component, and a non-return flap element (14) made of a second material component, wherein the first material component is harder than the second material component. The non-return flap element (14) includes a movable non-return flap (18), which is arranged such that it exclusively rests against the non-return flap element (14) or the ventilation device (10) is mountable on a vehicle component (28), wherein that part of the ventilation device (10) which engages the vehicle component (28) is part of the non-return flap element (14).

The wiper blade has a fastening part, a wiper lip and an elastically connected center part. The center part has a hollow space, which is bounded by two flexible walls. A stopper element is provided toextend in the hollow space based from the fastening part, and bounds the deformation of the center part, when the wiper blade is loaded with a deformed force. The stopper element has three-cornered cross-section, whose base surface represents in direction of the fastening part.

A device (10) for capturing a surface of an object (30) is provided, wherein the device (10) comprises a flexible membrane (14), which is configured to be deformed from a first shape to a second shape, when at least a part of the flexible membrane (14) is brought into contact with the surface of the object (30), wherein the device (10) comprises a plurality of strain-gauges (18) coupled to the flexible membrane (14), wherein the strain-gauges (18) are configured to measure a plurality of strain signals that depend on the shape of the flexible membrane (14), and wherein the device (10) comprises an output unit (24) for outputting the strain signals for reconstruction of the surface of the object (30) as a function of the strain signals.

A linear guide apparatus may include a guide rail, a carriage block, at least two recirculating tubes, and two end covers. The carriage block has an axial sliding channel formed at a middle portion of a bottom surface thereof, and the carriage block is slidably coupled on the guide rail through the sliding channel. Each of two sides of the sliding channel has at least a sliding groove formed between the carriage block and guide rail. Each sliding groove comprises a plurality of rolling balls installed therein so as to enable the carriage block to slide forward and backward on the guide rail. Each of the sliding grooves is cooperated with a recirculating channel axially penetrating through the carriage block. Each of the recirculating tubes comprises a plurality of spiral threads to enable the rolling balls to have lateral roll at a specific angle when passing therethrough.

The invention relates to a sealing diaphragm (1) and a check valve (9) comprising a sealing diaphragm (1) for fluid technology applications. A sealing diaphragm (1) for fluid technology applications is to be provided, which is economical and constructionally simple to produce, which can be used as a closing means for a check valve (9) and with which unwanted interfering noise can be prevented during operation. The object of the invention is achieved by a sealing diaphragm (1) with a flat, flexible sealing section, which can be bent or curved with a fluid pressure, wherein at least one resilient frictional tooth (4) is provided on or next to the surface of the sealing section at a distance from an edge of the sealing section, designed and arranged in such a way that it forms an angle between 30 degrees and 150 degrees with the sealing section and it tilts together with the bending or curving movement of the flat sealing section, wherein the frictional tooth has a contact surface (7) on a side orientated in the tilting direction. The object of the invention is also achieved by a check valve (9) for fluid technology outlet openings, comprising a housing part (10) having a fluid outlet (12), wherein an above-mentioned sealing diaphragm (1) is arranged in the flow path of the outlet opening, which is in contact with a sealing surface of a seal seat with a sealing section against the direction of flow and which can be bent or curved with a fluid pressure in the flow direction, wherein the contact surface (7) of the at least one frictional tooth (4) is simultaneously in contact with a corresponding bearing surface.
