An inlet valve recess (18) and an outlet valve recess (19) are aligned in a direction in which the upper surface (25) and the lower surface (26) are aligned.

A manifold block of vehicle braking system and vehicle are provided. The manifold block of the vehicle braking system comprises a hydraulic unit body, a solenoid valve mounting hole for mounting a solenoid valve, a sensor mounting hole for mounting a liquid pressure sensor and a simulator accommodation part for installing the pedal simulator.

The solenoid valve mounting hole, the sensor mounting hole and the simulator accommodation part are all arranged on the solenoid valve mounting face.

The invention has a purpose of obtaining a brake hydraulic pressure controller capable of securing durability with a simple configuration and a motorcycle brake system. The brake hydraulic pressure controller is a hydraulic pressure controller for a vehicle brake system and includes: a base body that is formed with a channel filled with a brake fluid therein; a hydraulic pressure regulation valve that has a plunger and opens/closes the channel by translatory movement of said plunger; a drive coil that has a hollow section, is vertically provided in the base body in a state where one end of the plunger is inserted in said hollow section, and causes the translatory movement of the plunger to drive the hydraulic pressure regulation valve; and a coil casing that accommodates the drive coil. The coil casing includes a wall that covers at least a part of an apex of the vertically-provided drive coil, and the drive coil is pressed toward the base body by a projection formed in the wall.

The invention relates to a valve arrangement (10) comprising valves and coil arrangements (20), each coil arrangement (20) having two coils (110, 210) which are electrically connected to separate control units (100, 200). Each valve can be independently actuated by either the first coil (110) or the second coil (210) of the coil arrangement (20) associated therewith. The invention further relates to a brake system (400, 500) having such a valve arrangement (10).

A brake system to couple between brakes and actuators provides a modular format that allows a plurality of braking modules to be coupled together at interfaces and coupled to other modules to handle a variety of different braking scenarios. Each braking module includes a housing forming a manifold for the delivery of fluid to the interfaces of the modules for exchange between the modules. The braking modules include a hydraulic valve coupled with a pressurized fluid source for delivering fluid to implement a braking function. The modules also include an electro-hydraulic valve configured for receiving electrical input signals and configured for delivering fluid from the pressurized fluid source to the hydraulic valve at an actuation pressure that is proportional to the system pressure based on the levels of the received electrical input signals. Module interfaces are positioned on respective sides of the housings for coupling the braking modules together and include a repeated pattern of apertures for aligning between the braking modules. The aligned apertures are configured for passing fluid at the system pressure and fluid at the tank pressure between the plurality of braking modules.

In a hydraulic unit, which is for a hydraulic brake system, that has a hydraulic block and at least one valve device, the valve device includes a hydraulic cartridge with a valve seat and with a movable closing body for blocking and opening the valve seat, and a magnet assembly with a magnet coil for generating a magnetic force for moving the closing body. The magnet assembly is integrated into the hydraulic block, and the valve device has a permanent magnet in order to assist the movement of the closing body by means of magnetic force.

A manifold block of vehicle braking system and vehicle are provided. The manifold block of the vehicle braking system comprises a hydraulic unit body, a solenoid valve mounting hole for mounting a solenoid valve, a sensor mounting hole for mounting a liquid pressure sensor and a simulator accommodation part for installing the pedal simulator. The hydraulic unit body is provided with a solenoid valve mounting face. The solenoid valve mounting hole, the sensor mounting hole and the simulator accommodation part are all arranged on the solenoid valve mounting face.

An electronic-pneumatic braking system for a vehicle, for example for a heavy goods vehicle or an articulated truck, includes a TCS/ESC modulator (1), enabling control functions for a traction control system (TCS) and a vehicle stability control system (ESC). The TCS/ESC modulator (1) includes a pneumatic relay valve (2), a solenoid valve (7) and a changeover valve device (11). In order to achieve a compact size and cost savings during manufacture, only control pressure can be applied to the solenoid valve (7) and to the changeover valve device (1), while only the pneumatic relay valve (2) has a large nominal size for conveying the supply pressure to at least one wheel brake and for venting the latter. As a result, the changeover valve device (11) can be structurally integrated in a TCS/ESC modulator (1) intended for carrying out the TCS/ESC functions.

A structure for forming a fluid path is provided. The structure for forming a fluid path according to one embodiment of the present disclosure includes a body configured with first and second fluid paths which communicate with each other, and a third fluid path which is provided at a position, at which the first and second fluid paths are connected to each other, and communicates with the first and second fluid paths, and includes one or more among a first ball which is able to be disposed in the first fluid path, a second ball which is able to be disposed in the second fluid path, and a third ball which is able to be disposed in the third fluid path, wherein a diameter of the first fluid path is greater than that of the second fluid path, and the second ball is able to be disposed in the second fluid path by passing the first fluid path.
