摘要： This invention relates to a flange-type stop cock having a ball valve plug. This ball-valve stop cock is so constructed as to have the same profile or outline as the flange portion of the existing flange-type stop cock having a conical-shaped valve plug. The flange mounting holes and the input and the output fluid openings are designed to conform with that of existing pipe seat brackets so that the present ball-shaped plug stop cock is a direct replacement for the conical-shaped plug stop cock.

摘要： Three-position solenoid valve which outputs an output pressure and can adopt exhaust, overlapping and supply positions. The output pressure is detected by an output pressure sensor and is fed back to a fuzzy control unit. Based on the difference between the output pressure and the command pressure corresponding to the pressure command signal from the brake control unit, such fuzzy control unit calculates a command current value for controlling the three-position solenoid valve by fuzzy reasoning. The command current value can adopt an essentially continuous value, and consequently the three-position solenoid valve can adopt a gentle exhaust state or a gentle supply state. In this way, sudden changes in the output pressure can be suppressed and the output pressure can be made to converge rapidly on the command pressure and eliminate overshoot and undershoot.

摘要： A three-position solenoid valve that can be used as a normally open type that can prevent reduction of responsivity due to the working pressure acting on a guide cylinder. When the solenoid is demagnetized, it is made to adopt a connecting position and since the working pressure does not act on the guide cylinder that guides the sliding of the moving iron core of the solenoid in this connecting position, it is possible to prevent deformation of the guide cylinder by the working pressure, which would reduce the responsivity of the solenoid valve and reduce the longevity of the solenoid by having the working pressure acting on it for long periods. Thus, it is possible to provide a valve that is suitable for use as a normally open three-position solenoid valve.
摘要翻译：可用作常开型的三位置电磁阀，可以防止由于作用在导向气缸上的工作压力而引起的响应性降低。当螺线管退磁时，使其成为连接位置，由于工作压力不会作用在导向筒上，引导筒在该连接位置引导螺线管的移动铁芯的滑动，所以可以防止变形引导筒通过工作压力，这将降低电磁阀的响应度，并通过使工作压力长时间作用在其上来减少螺线管的使用寿命。因此，可以提供适用于常开三位置电磁阀的阀。

摘要： A fluid pressure control device having a 3-position solenoid valve which is controlled to switch between a supply position, an overlapping position, and an exhaust position, using a drive command value corresponding to a pressure command signal. It also has a drive command setting unit which computes a drive command value for driving the 3-position solenoid valve into a predetermined position, in order to make the pressure command signal and a feedback signal of the output pressure of the 3-position solenoid valve coincide and a compensating value setting unit which computes a compensating value to be added to or subtracted from the above-mentioned drive command value, in accordance with the pressure differential between the above-mentioned pressure command signal and feedback signal, and the proportion of change in the feedback signal. The fluid pressure control device further has an addition and subtraction processing unit which computes a compensation amount by integrating the compensating value output from the compensating value setting unit when the drive command value has strayed from the overlapping command value corresponding to the overlapping position of the 3-position solenoid valve, and adds or subtracts the above-mentioned compensation amount to or from the drive command value, in the direction departing from the above-mentioned overlapping position, so as to output a new drive command value to the 3-position solenoid valve.

摘要： A tube seat installation device having a piping connecting part of a special coupling joint being attached on one side of the input piping opening or the output piping opening of the fluid pressure valve while at the same time having a cylindrical part of the special coupling joint fitted into a connecting hole of the tube seat via an O-ring sealing element. The piping connecting part of the special coupling joint is attached to the other side of an outlet piping opening or an inlet piping opening. The cylindrical part is fitted into the introduction part of the hollow body via an O-ring sealing element, or the introduction part of the hollow body is attached to the piping opening via an O-ring sealing element. A flange part of this hollow body is faced and fixed to another connecting hole of the tube seat via O-ring sealing element to which a fluid pressure valve is fixed by being sandwiched by the hollow body. A fluid path runs in the vicinity of the fluid pressure valve through a passageway so that it becomes possible to accommodate the flanges of different types which can be installed on a tube seat simply by using standard and inexpensive fluid pressure valves which have a piping opening fitted for a screw thread connection, and which can be mass-produced as a standard product.

摘要： The present invention provides a ball cock for a railway vehicle which comprises a main body possessing a primary-side opening and a secondary-side opening which face one another and an air exhaust aperture which is formed between these openings. Such ball cock further includes a ball-shaped valve body which is rotatably provided inside such main body and in which there is formed a communication aperture which connects the primary side opening and the secondary-side opening and a side aperture which, consequent to its rotation, connects the air exhaust aperture and either the primary-side or secondary-side opening. There is formed in the main body's air exhaust aperture a pipe connection to which is be connected a restrictor. In another embodiment a extension pipe is connected to such pipe connection in such air exhaust aperture. Such pipe extension forms a bend portion which causes its opening surface to be positioned lower than a generally horizontal direction when, in accordance with the state in which the main body is fitted to a railway vehicle, its air exhaust aperture is positioned upwardly from such horizontal direction.

摘要： A brake device equipped with an actuator having a power-transmission member generating a pushing force by receiving a drive force so as to advance. A pressure-detection device is provided for detecting the reaction pressure being applied to the power-transmission member and a clearance controller is provided for making the power-transmission member perform a return stroke. A brake shoe is attached to the power-transmission member and generates a braking force on the wheel tread surface. Such clearance controller is provided with a stroke memory unit which detects when the pressure signal from the pressure-detection device has reached a reference value when the pushing force of the power-transmission member is output and memorizes the stroke position of the power-transmission member as the reference stroke position. A computational processor determines the return stroke position by which the power-transmission member is separated from the wheel tread surface and the clearance stroke fraction established in advance using the reference stroke position, when the pushing force is released.

摘要： A fluid pressure device for detecting two or more fluid pressure levels from a varied range of fluid pressure includes a housing having a cylindrical bore and a pressure inlet in communication therewith. A piston member is reciprocably movable within the cylindrical bore. A piston rod extends from the piston member and projects outward of the housing where a switch-operating arrangement is secured. The switch-operating arrangement includes an interlocking arm and a number of blocking elements corresponding to the number of switch devices to be operated. Guide slots formed in the interlocking arm allow adjustment of the position of the blocking elements, thus affecting a change in the operating points of the switch devices. Surrounding the piston rod within the housing is a multiple-spring arrangement which opposes the movement of the piston and which exhibits a nonlinear spring coefficient. The multiple-spring arrangement includes a plurality of springs arranged serially and a plurality of middle body members disposed between the plurality of springs for limiting the compression on the plurality of springs.
