The present disclosure provides a system and a method for controlling kick-back in an electric booster type brake system capable of reducing a kick-back phenomenon in which a hitting force is transmitted to a brake pedal due to a difference between a high braking hydraulic pressure already generated in a power piston of a second master cylinder by driving a motor and a low braking hydraulic pressure generated in a first master cylinder when a driver steps on a brake pedal, in a fall back situation in which electric power is not smoothly supplied to the motor due to a low voltage of a battery.

A noise damper for a compressed-air system, for a brake system of a utility vehicle, including: a housing having an inlet channel for a compressed-air stream and with a chamber for accommodating sound-damping material, in which the inlet channel and the chamber are separated, perpendicularly with respect to the compressed-air stream, by a separating plate which is closed in a central region and which, in an outer peripheral region of the compressed-air stream, has multiple openings for introducing the compressed air directly into the chamber. Also described are a related pneumatic brake system and method.

A hydraulic valve assembly for a work vehicle includes a fan and brake function module. A first pump supplies hydraulic pressure to a fan circuit and to first and second service brake circuits of the vehicle. A second pump supplies hydraulic pressure to a steering and work function module that in turn supplies hydraulic pressure to a steering circuit and a work function circuit of the vehicle. The hydraulic valve assembly may also include a work control module and an auxiliary module. The modules of the hydraulic valve assembly are separably connected together via interface surfaces.

A pressure medium unit, in particular for setting and/or regulating a brake pressure in a vehicle brake system having electronic slip regulation, and to a cap-shaped filter element. Pressure medium units are equipped with a housing block having a duct formed therein that conducts pressure medium, a control element that controls a cross-section of the duct, and a filter element assigned to the control element and fixed in the interior of the duct. According to the present system, the filter element is formed in the shape of a cap, and has on its outer circumference a radially protruding fixing segment having an elastically deformable cross-section. A fixing segment realized in this manner compensates differences in expansion between the components caused by changes in temperature, prevents play at the filter element, and provides a particularly good filter effect.

An assembly may be provided that may include a valve body having a piston within a piston bore in the valve body, the piston bore including a valve chamber section and a brake pipe section such that a pressure differential between the valve chamber section and the brake pipe section moves the piston within the piston bore. The assembly may also include a slide valve seat coupled to the valve body. The slide valve seat may include a brake pipe port, an additional discharge channel pilot valve port, and at least one exhaust port, and a slide valve coupled to the piston and configured to move along the slide valve seat with the piston. The slide valve may be configured to move between at least a piloting position and an exhaust position to vary an exhaust rate of the brake pipe section and an exhaust rate of the valve chamber section during braking.

The present disclosure provides a system and a method for controlling kick-back in an electric booster type brake system capable of reducing a kick-back phenomenon in which a hitting force is transmitted to a brake pedal due to a difference between a high braking hydraulic pressure already generated in a power piston of a second master cylinder by driving a motor and a low braking hydraulic pressure generated in a first master cylinder when a driver steps on a brake pedal, in a fall back situation in which electric power is not smoothly supplied to the motor due to a low voltage of a battery.
