摘要： The present invention provides a booster in which magnitude of output can be adjusted also by an operation of a solenoid mechanism. An armature (13) is shifted to the right (in FIG. 1) in opposition to a returning spring by applying electricity to a solenoid (39), with the result that a space (80) on one end of the armature is communicated with a constant pressure chamber (5) through a passage (T3). When an electromagnetic force acting on the armature (13) exceeds a predetermined value, a distal end of a valve member (28) is shifted to the right (in FIG. 1) via a cylindrical member (31) to open an atmospheric valve (34), thereby introducing the atmosphere into a variable pressure chamber (6). The pressure in the variable pressure chamber is applied to the other end of the armature and the difference in the pressure tends to move the armature toward its home position.

摘要： The present invention provides a brake booster that, although simple in construction, capable of adjusting the braking force derived by operation of a solenoid mechanism without worsening the braking response. In the brake booster according to the present invention, when a movable member (34) is shifted toward the rear side by electromagnetic force of a solenoid (31), the shifting movement is transmitted to a valve seat member (21) through pins (50) to open an atmospheric valve (27) through which air is introduced into a variable pressure chamber (9,10), whereby a pressure difference is created between the variable pressure chamber and a constant pressure chamber and generates booster output (thrust output force). In the present invention, pressure in the constant pressure chamber is introduced into a chamber (54) formed at one end of the movable member (34) through a passage (56), and atmosphere is introduced into a chamber (55) formed at the other end of the movable member (34) through a passage (57), thereby exerting on the movable member (34) a reaction force caused by the pressure difference between the variable pressure chamber and the constant pressure chamber. Thus, the booster output becomes proportional to the electric current supplied to the solenoid (31). Further in the present invention, the size of the passage (57) is determined properly so as to limit air introduced therethrough into the chamber (54) and keep the reaction force small until the booster output reaches an adequately level, thereby preventing the breaking response from deteriorating.

摘要： The present invention provides a control booster which is capable of appropriately detecting a pedal-operated brake operation during an automatic brake operation. For moving a stop key from a position on a side of a rear-side abutment surface (where a reaction force of a switch acting on a switch operating rod and a spring force of a switch spring are balanced) toward an intermediate position, when the stop key is located on a side of the rear-side abutment surface, only a return force of the spring acts on a contact operating element of the switch. On the other hand, when the stop key moves toward the intermediate position, an abutment portion is separated from the contact operating element (that is, the switch operating rod moves in a direction for separation relative to the switch), so that no load is applied to the contact operating element. Breakage of the switch can be avoided when the brake pedal is operated during the automatic brake operation and operation of the brake pedal can be detected from the turning-off of the switch.

摘要： In a cylinder body of a cylinder apparatus of the present invention for a brake fluid pressure control system, primary and secondary pistons having different pressure-receiving areas are provided. A pressure chamber between the primary and secondary pistons is communicated with a reservoir through flow passages formed between the cylinder body and a sleeve and between the sleeve and the secondary piston. In normal operation of the brake fluid pressure control system, the cylinder apparatus serves as a stroke simulator by releasing the fluid in the pressure chamber through the flow passages to the reservoir and contracting a spring in the pressure chamber. In the event of a failure of the system, the cylinder apparatus serves as a tandem master cylinder in which the flow passages are closed by a seal member in accordance with movement of the secondary piston, and the primary and secondary pistons move, while substantially no contraction of the spring in the pressure chamber occurs.

摘要： When a stroke speed exceeds a reference value of a stroke speed threshold value, a solenoid is energized to tract an armature, thereby opening an atmospheric valve independently of the position of a plunger. Consequently, power pistons, together with an output rod, are moved forward by a thrust corresponding to a pressure difference between a constant-pressure chamber and a variable-pressure chamber to perform a full-power braking operation. A reaction-adjusting mechanism contributes to an improvement in safety by functioning in such a way that when the part of the reaction force from the output shaft that is transmitted to an input rod reaches a predetermined value, a boosting ratio is increased, so that the reference value of the stroke speed threshold value can be set high to prevent unnecessary braking.

摘要： The present invention presents an economical fluid pressure control device particularly applicable to controlling the fluid pressure in the wheels of an automobile provided with an antiskid capability so that the unpleasant pedal kickbacks are prevented under various operating conditions of the wheels. This is achieved by providing at least two wheel cylinders for one pressure generation source, a reservoir and a pump. A flow valve provided on each of the wheel cylinders is provided with a simple flow switching device which control the position of a spool, disposed inside the flow valve, which assumes a stationary position for non-antiskid operation mode and a operation position for antiskid operation mode. When one of the wheels is in the antiskid operation mode, and the other wheel is in non-antiskid operation mode, the brake fluid discharged from the pump is not allowed to enter the flow valve disposed in the non-antiskid operation mode. Therefore, the fluid pressure pulsations generated in the fluid circuit in the antiskid operation mode are not transmitted back to the pressure generation source through the flow valve in the non-antiskid operation mode. Therefore, there in no transmission of unpleasant pedal kickbacks at the pressure generation source.

摘要： A master cylinder realizes a stroke simulator function without the need to change the structure around a brake pedal and without impairing brake pedal feel, is easy to form by machining, and also facilitates a hydraulic fluid charging and air bleeding operation. A secondary piston is split to make the axial length thereof variable, thereby imparting the stroke simulator function to the secondary piston. By doing so, brake pedal feel is improved more than by separately adding a stroke simulator.

摘要： A fluid passage switching valve includes a core structure provided with an input passage extending from an input port. The input passage opens on an outer peripheral surface of the core structure at such a position that when a plunger is in a fluid cut-off position, the input passage is closed by an inner surface of the plunger, and as the plunger moves toward a fluid passing position, the input passage is opened and communicated with an input port-side fluid chamber. An output port is communicated with an output port-side fluid chamber. The plunger has a communicating bore which provides communication between the input and output port-side fluid chambers. The pressure-receiving area of the plunger in relation to the input port-side fluid chamber is approximately the same as that of the plunger in relation to the output port-side fluid chamber over the entire travel range of the plunger. A seal device blocks communication between the input passage and the input port-side fluid chamber when the plunger is in the fluid cut-off position.
