摘要： A pneumatic-controlled device for a vacuum brake booster having a hollow piston which retains a tubular shut-off member. The tubular shut-off member interacts with a stationary seat and a movable seat to define a chamber within the hollow piston when the movable seat is in an actuation position. An orifice formed in the tubular shut-off member places the chamber in communication with a passage defined between the stationary and movable seats to reduce hysteresis experienced by movement of the movable seat.

摘要： The invention relates to a pneumatic brake booster using two sources of air pressure and comprising a rigid casing (3) divided by a leaktight moving partition (4) into at least two chambers (3a, 3b), it being possible for the moving partition to be urged by a difference, brought about by an actuation of the valve, between the pressures supplied to the chambers in order to drive along a pneumatic piston (5) bearing an operating valve (7), the inside (50) of this piston being separated from the second source by a purification filter (14). The booster of the invention includes shut-off means (16, 51) with controlled opening, installed between the second source of pressure (A) and the inside (50) of the piston and controlling an air intake path (15) which connects the second chamber (3b) to the second source of pressure (A) avoiding passing through the filter (14) and the valve (7), and elastic means (17) which are sensitive to a difference in pressure between the inside of the piston and the second source of pressure, in order to allow selectively the opening of the shut-off means when this pressure difference exceeds a given threshold.

摘要： A pneumatic booster (1) having casing (3) divided by a movable partition (3) into first (3a) and a second (3b) working chambers. The movable partition (4) being urged by a pressure differential derived from a first fluid pressure in the first working chamber (3a) and a second fluid pressure in the second working chamber (3b). The second fluid pressure is communicated to the second working chamber (3b) through the actuation of a shutter (70) by means of a plunger (8). The shutter (70) has freedom of movement with respect to the plunger (8) while being elastically urges against the plunger (8). The shutter (70) is connected to a mass (15) which is set in motion by a movement of the plunger (8). The mass (15) thereafter acts on and moves the shutter (70) away from the plunger (8) to increase the flow of the second fluid pressure to the second chamber (3b).

摘要： A pneumatic brake booster having a casing (10) with an axis of symmetry (X-X') divided in a leaktight fashion by a moving wall structure (12) into a front chamber (14) and a rear chamber (12). The front chamber (14) is permanently connected to a source of low pressure and the rear chamber (12) is connected selectively to the front chamber (14) or to a source of high pressure by a three-way valve (36). The three-way valve (36) is actuated by a control rod (30) capable of bearing via a front face of a plunger (28) on a rear face of a push rod (48) secured to a reaction disk (49). The plunger (28) slides in a bore (26) of the moving wall structure (12) in response to an input force applied by an operator. The three-way valve (36) includes a valve element (36) located in a tubular rear part (22) of the moving wall structure (12) and interacts via with a first annular region (40l) of an annular front face (40) with a first annular valve seat (28a) formed on the plunger (28) and via a second annular region (40e) of the annular front face (40) with a second annular valve seat (20a) formed on the moving wall structure (12). The first valve seat (28a) is concentric with the second valve seat (20a) and of a smaller diameter. The annular front face (40) of the valve element is urged toward the annular valve seats (20a, 28a) by a valve spring (42) and is reinforced by a rigid annular insert (46,46'; 56,56'). The rigid annular insert (46,56) is situated axially behind just one (40e) of the regions (40e, 40i) via which the annular front face (40) of the valve element (36) interacts with one (20a) of the annular valve (20a, 28a).

摘要： A pneumatic servomotor (1) for an assisted braking having a housing, separated by a diaphragm (5) into a first variable-volume chamber (3) and a second variable volume chamber (7) therein. During a. brake application a force applied to a control rod (13) moves to allow a first flap (19) to isolate the second chamber (7) from the first chamber (3) and thereafter allow a second flap (23) to open and allow pressurized assist fluid to be communicated to the second chamber (7). The diaphragm (5) has a lip (35) thereon that engages the housing to define a thrust chamber (41). On opening of the second flap (19) allows the pressurized assist fluid is initially communicated to the thrust chamber (41) and only after a predetermined travel of the control rod (13) is the pressurized assist fluid communicated to the second chamber (7) for creating a pressure differential between the fluid in the first chamber (3) and second chamber (7) to develop an output force to effect a brake application. On termination of the input force to the control rod (13) the lip (35) provides for one-way isolation to permit the discharge of the assistance fluid from second chamber (7) to allow for equalization of fluid pressure in the first (3) and second (7) chambers.

摘要： A pneumatic booster having a casing (16) formed from a cylinder (32) and a cover (34). The casing (16) is divided into two chambers (18,20) by a movable wall (10). The movable wall. (20) has a plate (12) and a flexible membrane (14). A bead (30) on the outer peripheral edge of flexible membrane (14) is fixed to the casing (16). The flexible membrane (14) forms a fold in a space located between the peripheral edge of the plate (12) and the casing (16). The plate (12) is secured to a hub structure which houses a valve member for operating the pneumatic booster. The plate (12) which is substantially parallel to the end cover has an extension (40) that extends in a forward direction substantially concentric to the cylinder (32). The extension (40) has front part (46) and a rear part (44) with a radial shoulder (42) on the front part. The radial distance (D) between the rear part (44) and the cover (34) is substantially equal to the radial distance between the front cover part (46) and the cylinder (20) minus the thickness of the membrane (14). Thus the movable wall (10) defines a maximum active surface for the development of an operational force in response to the development of a pressure differential upon actuation of the valve member.
