    摘要: An oscillation damper that has a cup-shaped elastomer diaphragm body, with a bottom diaphragm. The diaphragm body is received tightly on an opening side in a bore of a housing, and fits around a protrusion of a closure body that closes the bore. Between the closure body and the diaphragm, a support body having an end face that is concave toward the diaphragm is received in the diaphragm body. A void formed between the diaphragm and the support body communicates with the atmosphere, through a conduit embodied on the support body and through an opening in the closure body. The oscillation damper can be used in hydraulic slip-controlled motor vehicle brake systems.

    摘要: An objective for use in photographic compact cameras has a relative aperture of 3.5 and a focal length of 35 mm, and is of the triplet type. The lens element on the object side is a cemented element. In order to achieve an extremely compact structural shape and balanced monochromatic correction, as well as a reduction in the chromatic magnification difference, the color coma and the color astigmatism, four design conditions are specified.

    摘要: A pressure limiting valve has a valve closing member (ball), which is subjected to a hydraulic opening force and is indirectly subjected to a closing force generated by a compression spring which avoids hysteresis that impairs the switching behavior of the pressure limiting valve. A tappet, which passes through a sealing ring and is exposed to a control pressure, is also capable of acting in a closing manner upon the pressure limiting valve. When there is no operative control pressure, the tappet is pushed back by the opening of the pressure limiting valve and is retained in this position by frictional forces brought about by a sealing ring. The switching plays of the pressure limiting valve are free of frictional forces. The pressure limiting valve is suitable for use in hydraulic motor vehicle brake systems.

    摘要: A hydraulic system having a pressure generator which is protected against destructive overload. The hydraulic system has a pulsating feeding pressure generator, such as a piston pump, which feeds pressure fluid at high pressure into a damper chamber of a housing. A throttle body having a throttle bore is disposed on the outlet side of the damper chamber. For producing the protective effect, the damper chamber is preceded by a rupture disk communicating with the outlet. The throttle body suitably has a thin-walled portion, embodied as a rupture disk, in which the throttle bore is located. The embodiment described is advantageously usable in hydraulic systems in which pressure fluids are pulsatingly fed at high pressures.

    摘要: A tandem master cylinder which has a compensating bore in communication with a chamber on the rear side of the master piston. The bore is provided in the front wall of master cylinder piston and is adapted to be closed by means of valve body movable relative to said master cylinder piston. The valve body is provided on the end of a central clamping element interconnecting the two spring retainers of a piston restoring spring of master cylinder piston. The valve body is urged against compensating bore as soon as the piston restoring spring is loaded. In order to maintain a predetermined filling pressure in the chamber behind the master cylinder piston and in the output position of the piston in pressure chamber, the piston restoring spring is supported on a spring retainer that is held through a stop on the cylinder housing.

    摘要: In a mirror reflex camera (1) having a viewer system consisting of a focusing screen (4), a field lens (5) a pentaprism (7) and an ocular (6) and with an electronic range finder (9, 10a10n), an optical means (11) defining a measuring spot is arranged in the plane of the focusing screen for the purpose of splitting the exit pupil (AP) of the picture-taking objective (2). This optical means is a clear-glass wedge and splits a partial beam (12) off the viewer beam (8). This partial beam serves to generate, upon its reflection from the surfaces 7b and 7a of the pentaprism (7) and from the concave mirror 7d ground on the lower edge of the exit side 7c, an image (B") of the object onto the lens elements 10a-10n of the array (9)of photoelectric detectors. The outer bounding 30 of the concave mirror 7d is selected to be rectangular or square and the radii of the lens elements (10a-10n) are such that only one particular pair of detectors of the array (9) of photoelectric detectors is impinged by light from the lens elements 10a-10n.

    摘要: A system for determining photoelectrically the position of at least one focus plane of an image within an optical apparatus, wherein the object is reproduced at least at one spatial frequency filter of an optical image correlator and there is measurement and/or display of the light fluxes leaving the local frequency filter.In this system light fluxes traversing differing pupil sections of the reproducing optics are modulated in common by a spatial frequency filter and are split up geometrically or physically, or by means of additional modulation in correspondence with the pupil sections. They are consecutively or simultaneously projected on a common photoelectric receiver or on separate photoelectric receivers, the output signals of which are processed further for purposes of controlling display and/or follow-up devices.
