Abstract: Afin d'éviter à un véhicule équipé de dispositifs d'assistance de freinage et de correction de trajectoire et présentant un centre de gravité haut placé de se retourner dans une courbe lors d'un brusque coup de volant simultanément à un brusque freinage, un circuit hydraulique de freinage comprenant une pompe hydraulique (3) qui aspire un liquide contenu dans un réservoir (3) à travers un maître-cylindre (1), est pourvu d'une vessie (10). La vessie, placée entre le maître-cylindre et la pompe hydraulique, diminue la durée d'écoulement du liquide hydraulique vers la pompe, en assurant une pression d'aspiration suffisante à l'entrée de la pompe afin de gaver le frein et de faire glisser la roue ayant le plus d'appui.

Abstract: The invention relates to a pressure accumulator, especially a pulsation damper, which comprises an accumulator housing (10) and a piston element (28) disposed therein. A bellows-type separative element (30) is supported on the piston part (28) with its one end (32) and with its other end (34) on the accumulator housing (10). Said separative element (30) separates two working chambers (26, 40) within the accumulator housing (10) from each other, especially a gas chamber (26) from a fluid chamber (40), in a fluid-tight, especially gas-tight manner. The one working chamber (26), in addition to a defined volumetric proportion of a working gas, is filled with a fluid. In this manner the working gas allows for a compression to a certain degree and thus for a dampening and smoothening of the pulsations of the fluid medium migrating to and occurring on the fluid side of the accumulator.

Abstract: The invention relates to an accumulation chamber for a hydraulic vehicle braking system. According to the invention, the accumulation chamber is configured as a gas separator (32) comprising two connections for fluid located at different heights (36, 38). Wheel braking cylinders of an energy-assisted braking system are connected to the lower fluid connection (38). Said cylinders can be actuated by muscular force, if a service braking system operated by external energy malfunctions. The gas separator (32) keeps gas bubbles away from the lower fluid connection (38), thus preventing gas bubbles from reaching the brake fluid of the energy-assisted braking system operated by muscular force, to guarantee the operation of the latter.

Abstract: A hydraulic circuit includes an accumulator having an inflow passage which introduces a hydraulic fluid which is discharged from a hydraulic pump into a hydraulic fluid chamber and a discharge passage which discharges the hydraulic fluid from the hydraulic fluid chamber to a hydraulic actuator. The hydraulic circuit includes a valve mechanism which restricts the supply of hydraulic fluid from the hydraulic fluid chamber to the hydraulic actuator when the pressure in the hydraulic fluid chamber is less than a set pressure and which releases the restriction of the supply of hydraulic fluid to the hydraulic actuator when the pressure in the hydraulic fluid chamber is at least the set pressure. The valve mechanism may be installed inside the accumulator.

Abstract: In the interior of the housing (15) of an accumula­tor (10), a metallic bellows (30) and a self-seal mechanism (37) are arranged. The metallic bellows (30) partitions the interior of the housing (15) into a gas chamber (45) and a liquid chamber (41). The self-seal mechanism (37) includes an elastic seal member (35) and a face (36) which the elastic seal member (35) opposes. When the bellows (30) is compressed to the predetermined extent due to introduction of a compressed gas into the gas chamber (45), the elastic seal member (35) is brought into contact with the face (36), thus closing a flow port (18). The elastic seal member (35) has a slanted face (52), so that a wedge-shaped liquid guide gap (55) is produced when the elastic seal member (35) is in contact with the face (36). When, in this con­dition, the compressed liquid is introduced into the flow port (18), part of the liquid enters the liquid guide gap (55), thus permitting the seal member (35) to easily separate from the face (36).
