Abstract: A bumper for an automobile includes a crossbeam which is formed from at least two separate hollow profiles, wherein the hollow profiles abut one another along a longitudinal wall and are joined with one another. The abutting longitudinal walls form a double web oriented in the longitudinal direction of the automobile. The hollow profiles may have an identical cross-sectional configuration. The hollow profiles may be roll-formed or extruded. The modular construction of the crossbeam from separate hollow profiles allows a lightweight construction and allows the load characteristic of the crossbeam to be functionally adapted to different requirements depending on the vehicle or vehicle class.

Abstract: A bumper system includes a crossbeam having ends constructed to form attachment zones, and two crash boxes which are secured to side rails of a motor vehicle and coupled to the attachment zones, respectively. The crossbeam has a front wall, a rear wall, and an inner wall which extends between the front and rear walls along a major length of the crossbeam. The inner wall is hereby recessed to leave a gap in the area of the attachment zones.

Abstract: A bumper for a motor vehicle includes a crossbeam having a hat profile defined by a bottom wall, legs respectively adjoining the bottom wall, and flanges respectively extending from the legs. The hat profile has sections of varying cross sectional configuration in a longitudinal direction. A face plate closes the hat profile to define a hollow space, with the crossbeam being mountable with the face plate such as to point outwards. An upper one of the legs has a width which is greater than a width of a lower one of the legs in a center section of the crossbeam. The crossbeam has curved ends oriented in a direction of the motor vehicle, and the face plate includes in the center section a stiffening embossment which is oriented into the hollow space defined by the hat profile and the face plate.

Abstract: A bumper for a motor vehicle includes a lightweight cross member attachable transversely to the longitudinal rails of the motor vehicle frame. The cross member includes two longitudinal profiles which are displaceable relative to each other and support each other during the displacement. The bumper provides improved functionality and increased energy absorption capability.

Abstract: A bumper of a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame and has a U-shaped cross section formed by a wall and two legs extending from opposite ends of the wall Extending longitudinally in a direction of the cross member is a reinforcement member which has a T-shaped cross section and closes off a front end of the cross member.

Abstract: A single screw compressor is arranged to vent the flutes of its main rotor at all times, without having to provide a check valve in the discharge port of the main rotor casing. An additional outlet port in the casing vents gas from the discharge ends of the flutes into the body of a slide instead of to the discharge port. The vented gas is guided to an exit port of the slide, from where it can reach either the discharge port or the bypass port of the casing at all times during use of the compressor and under all loading conditions. The design of the slide further allows the use of an offset •? discharge port in the casing, in relation to the main rotor. This means that pressure acting through the discharge port in use of the compressor tends to press the slide against another structure than the main rotor, for instance a bearing housing, giving better support to the slide. The slide also provides an improved oil delivery arrangement.

Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame. A crash box is incorporated between the cross member and the side rail, with set bolts being provided to join the crash box to the cross member in the absence of prepunching.

Abstract: A bumper of a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame and has a U-shaped cross section formed by a wall and two legs extending from opposite ends of the wall Extending longitudinally in a direction of the cross member is a reinforcement member which has a T-shaped cross section and closes off a front end of the cross member.

Abstract: A bumper for a motor vehicle includes a cross member extending transversely to side rails of a vehicle frame. The cross member has a U-shaped cross section which is defined by a web connected on opposite ends to two legs, respectively, and configured to point in a direction of the motor vehicle. The web has a reinforcement embossment in a central length section of the cross member.

Abstract: A device and method to accurately measure the anatomy of a patient undergoing a radiographic procedure, utilizing a sphere of known dimensions attached to a flexible member, wherein the sphere is manipulated into the correct position and remains stationary during the procedure.

Abstract: A bumper system of a motor vehicle includes a bumper beam for connection to a side rail. The bumper beam has a center portion and an end portion which adjoins the center portion and extends beyond the side rail. The end portion is curved or angled in a direction of the side rail and having an outer end. Positioned at the outer end of the end portion is a containment element which extends transversely to a longitudinal center plane of the motor vehicle.

Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to side rails of a motor vehicle frame and connected to the side rails via crash boxes. The cross member has a C-shaped cross section and includes an outer shell member and an inner shell member. The inner shell member is constructed as tension link which is made of a material having a tensile strength that is greater than the tensile strength of a material of the outer shell member.

Abstract: A valve comprises a housing (1) having an inlet (4) and an outlet (5), and a pressure sensing port (8). A piston (6) slides in a part (3) of the housing (1) in response to a difference between a first fluid pressure at the pressure sensing port on the one side of the piston, and a second fluid pressure at the inlet and/or outlet on the other side of the piston (6). A valve member (7) carried by the piston is operable thereby to close the inlet (4) when said second fluid pressure is less than a value sufficiently greater than said first fluid pressure. The valve member (7) is movable with respect to the piston (6) to facilitate closing of the inlet (4), in response to a fluid flow from the housing (1) to the inlet (4), when the piston is not acting to close the inlet.

Abstract: A bumper for a motor vehicle includes a cross member which is disposed transversely to a side rail of a motor vehicle frame, and a crash box which is connected between the side rails and the cross member. The crash box is configured in fold construction from a metal sheet and has a sidewall which exhibits a roof-shaped structure. The sidewall includes at least one wall section which is inclined in relation to the horizontal midsection transverse plane of the crash box.

Abstract: A bumper for a motor vehicle includes a cross member disposed transversely to side rails of a motor vehicle frame and having a U-shaped cross section with a wall and two legs extending from opposite ends of the wall. The cross member is supported via integral crash boxes against the side rails. Each crash box has a cross member proximal end which abuts against the wall of the cross member, and includes vertical legs and horizontal legs to define a casing-like configuration. The wall of the cross member is formed in an area of the cross member proximal end of the crash box with a depression which extends in a direction of the crash box, with the vertical legs of the crash box joined at the cross member proximal end to the wall of the cross member, and with the horizontal legs of the crash box spaced from the wall of the cross member by a distance.
