Abstract: For producing a high pressure impulse, a hose bending valve is provided that comprises a loop (12) provided in a supply hose of an instrument (2) and a hose bending device (8) provided as multiple-use component. Such a valve is very simply constructed and allows the creation of steep pressure increase flanks with very high pressures up to 100 bar, as are needed for a needleless injection. The sterilization effort is minimal. Also, the material effort is minimal, if single-use components are used.

Abstract: An apparatus for supply of coolant, particularly CO2 that is preferably provided in bottles, to cryosurgical instruments. The device may be a mechanical or thermal compression device. A pump may supply the CO2 taken from the bottle in a buffer container with a desired operation pressure. The pressure in the gas bottle can be less than the desired operation pressure. The apparatus includes a tempering device that is configured to bring the coolant to a desired temperature, particularly a temperature that is higher than the temperature in the gas bottle or in another storage container.

Abstract: A sprag for a sprag-type freewheel clutch having a profile comprised of multiple profile sections, the sprag having at least the profile sections of an inner engagement curve, an outer engagement curve and a first and a second lateral curve, wherein the outer and inner engagement curves each form a component of a logarithmic spiral.

Abstract: A freewheel coupling (1) is provided having clamping bodies (4), which are arranged between an inner ring (2) and an outer ring (3) and which have a narrow section (5). A single cage (9) is arranged between the inner ring (2) and the outer ring (3) with a plurality of pockets (10). Each of the pockets (10) has an area (12) that is narrower in the axial direction and an area (11), which is adjacent to this narrower area, which is wider in the axial direction, and which is provided for holding a clamping body (4). A spring band (6), which is arranged radially within the cage (9), has an original curvature in the unloaded state, wherein the curvature radius exceeds a radius of the cage (9), and spring tongues (13), which are provided for spring mounting of the clamping bodies (4), are directed radially inwardly.

Abstract: A freewheel coupling (1) is provided having a gap (12) formed between a bearing inner ring (2) and a bearing outer ring (3). At least one of the bearing rings (1, 2) is constructed as a sleeve formed using a non-cutting method. Clamping bodies (6) are arranged in the gap (12) and have a throat (7). A spring band (13) with spring tongues (14), which are aligned tangentially, and which can be deflected in the radial direction, contact the clamping bodies (6) in the area of the throats (7). A cage (17) with recesses (18) that holds the clamping bodies (6) is arranged radially outside of the spring band (13) in the gap (12).

Abstract: In an overrunning clutch comprising clamping elements (5) arranged behind one another in peripheral direction between a circular cylindrical inner ring (1) and a concentric outer ring (2), said clamping elements (5) being guided in pockets (6) of a cage (9) while being loaded by spring tongues (7) of a band spring (4) that bears radially against the cage (9), each of the pockets (6) for receiving a clamping element (5) comprising a limiting wall (8) that enables a support of the clamping element (5) on the cage (9), the cage (9) comprises a reinforcing ledge (10) formed integrally on an outer surface of the cage (9) in every radial region comprising the limiting wall (8).

Abstract: A clamping body freewheel (1) has clamping bodies (2) arranged between a cylindrical outer raceway (4) and a cylindrical inner raceway (3) which is concentric with respect to said cylindrical outer raceway (4), which clamping bodies (2) can be tilted between a freewheel position and a clamping position, and has a cage (6) which guides the clamping bodies (2). The clamping bodies (2) are shaped and guided in the cage (6) in such a manner that they are raised both from the inner raceway (3) and from the outer raceway (4) into the freewheel position when a minimum rotational speed of the cage (6) is exceeded.

Abstract: A freewheeling clutch with clamping bodies arranged one behind another in the circumferential direction between a circular cylindrical inner ring and an outer ring concentric thereto. The clamping bodies are guided in pockets of a cage and are acted on by a band spring with spring tongues which bears radially against the cage. The band spring is annular and has punched cutouts arranged one behind another at spacings in the circumferential direction corresponding to the pockets of the cage and the spring tongues are formed by the cutouts. An empty pocket is arranged on the band spring between each two punched cutouts arranged one behind another in the circumferential direction.

Abstract: A rolling bearing cage comprising a first side ring (1) and a second side ring (2) that are connected to each other by crossbars (3) so that pockets (5) for receiving rolling elements (4) are formed, and lubrication grooves (6) extend in axial direction up to said first and second side rings (1, 2) on at least one of peripheral surfaces and bore sections of the crossbars (3) wherein flow channels (7) are arranged in a fractional region of the lubrication grooves (6) and are set back relative to the lubrication grooves (6) in at least one of a radially inward and a radially outward direction.
