摘要： A known device for increasing the functional reliability for a hydraulic circuit of a hydraulic clutch having a pressure reservoir (25) and a release cylinder (5) which comprises a primary piston (14) and a secondary piston (16). A compensation volume is developed in the sense that when the vehicle is at a standstill and the parking brake released, an unintentional release of the clutch is prevented. A pressure-monitoring/pressure-supply device (28) is used for determining a reference operating pressure and establishes a static pressure which, in case of any system error, only allows displacement of the secondary piston (16) such that the contact pressure of the clutch discs, against one another, is still sufficient to maintain the vehicle at a standstill.

摘要： A system for mounting or/demounting a cylinder unit (1) in a vehicle. A piston rod (5) provided with a piston (4) arranged in the bore (6) of the cylinder unit (1) which piston (4) and piston rod (5) are displaceably arranged in the axial direction of the bore (6) of the cylinder unit. The bore (6) has an opening (13) provided for an end portion of the piston rod (5) to protrude out from the bore, and the piston (4) separates the cylinder unit into a first chamber (7) and a second chamber (8) . At least a first passage (9) is provided for communication of fluid into or out of the first chamber (7) . In an initial operating position of the cylinder unit, the piston (4) and the piston rod (5) is positioned with the end portion of the piston (5) protruding out from the mouth of the bore (6). In a mounting/demounting position of the cylinder unit, pressuriized fluid is introduced into the first chamber (7) preferably through the first passage (9) thereby placing the piston (4) and the piston rod (5) in a mounting/demounting position where the end portion of the piston rod (5) essentially retracted in the bore. The invention also concerns a method for mounting/demounting the cylinder unit.

摘要： The present invention relates to a method of extracting a flow signal from echographic signals received from a region of interest comprising moving tissues and flowing fluids. The method comprises a step of calculating Doppler signals from said echographic signals within a small number of time samples, a step of separating first and second estimated Doppler signals from said calculated Doppler signals, a step of calculating a linear combination of said first and second estimated Doppler signals which locally maximizes a temporal coherence, a step of deriving a third and fourth estimated Doppler signals from first and second maxima of said temporal coherence, a step of classifying said third and fourth estimated Doppler signals into an estimated Doppler clutter and flow components. The method finally comprises a step of forming a motion image of the flowing fluids from said estimated Doppler flow component.

摘要： A hydraulic cylinder (10) is disclosed comprising a cylinder housing (12) with a housing bore (14), a piston (16) held longitudinally displaceably in the housing bore, a piston rod (18) allocated to the piston and a fixing element (20) which before a first cylinder operation is detachably connected with the piston rod and fixes this in a predetermined stroke position in relation to the cylinder housing and is designed to release the piston rod in relation to the cylinder housing on the first cylinder operation. According to the invention, before the first cylinder operation the fixing element in a first position is detachably connected with a center area (22) of the piston rod and on cylinder first operation can be moved from the first position to a second position area (24), in particular stationary in relation to the piston rod, in which it can be fixed for further cylinder operations. The result is a simply designed hydraulic cylinder in which the fixing element provided for temporary tying of the piston rod in particular leaves untouched the end of the piston rod facing away from the piston and also does not hinder further the operation of the hydraulic cylinder.

摘要： A piston arrangement for master and/or slave cylinders of a hydraulic actuating device for clutch and/or brake systems on motor vehicles is disclosed. An insert is inserted into a recess of the piston up to a first stop, the insert having a ball seat and an expandable insertion sleeve which is undercut with respect to the ball seat and protrudes with its expandable region. A ram is pushed into the sleeve with its ball end until it snaps into the ball seat. As the ram is further pressed axially, the insert slides over the first stop, is firmly pressed into a narrow hole section of the recess and strikes a second stop at the inner end of the recess. The insertion sleeve is then tightly enclosed by the piston wall and can no longer expand even in the event of very high pull-out forces, i.e. cannot release the ball end of the ram.

摘要： A device for rendering a hydraulic actuating device operational. A motor vehicle clutch with an emitter-receiver system located in the transmission path of the actuating device comprising two pistons whose positions, relative to one another, can vary as a function of the desired operating behavior of the actuating device and is developed further such that in relation to the emitter-receiver system that is to be filled with fluid, operationality can be established comparatively quickly and by simple way. A fluid supply unit (24) comprises one impulse valve (25) that serves to release an essentially constant volume flow, acted upon by an impulse valve control device (26) which is constructed such that the fluid volume flow released by the fluid supply unit (24) and flowing into the emitter-receiver system (5) does not exceed a limiting volume flow QK.
