    摘要: A valve unit (1.1, 1.2, 1.3) for modulating pressure in a compressed air braking system has an inlet valve (6) configured as a diaphragm valve, an outlet valve (7) configured as a diaphragm valve, and respective precontrol valves (8, 9), which are each configured as a 3/2-way solenoid valve and are arranged in an elongate valve housing (2), which is divided by a division plane (10) that is largely horizontal in the installation position into a base housing (11) and a housing cover (12). The precontrol valves (8, 9) are arranged in the housing cover (12) in the longitudinal direction (13), and the housing cover (12) has a centrally arranged magnet module (20) and two air guide modules (23, 24) adjacent to the magnet module (20) in the longitudinal direction (13) and connected via a single connecting element (45) both to each other and to the base housing (11).

    摘要: The invention relates to a valve unit for modulating the pressure in a pneumatic brake system, comprising a brake pressure inlet, a brake pressure outlet, a vent outlet, a diaphragm inlet valve, a diaphragm outlet valve, and a pilot valve for each diaphragm valve, the pilot valves being arranged in an elongate valve housing (having a main housing and a housing cover. The inlet valve pilot valve and the outlet valve pilot valve are arranged substantially centrally above the diaphragms of the inlet valve and the outlet valve in the housing cover and with the actuation axes of the pilot valves running parallel to the parting plane, and the housing cover includes a central insert which has valve bores and control channels and into which the solenoids and the mechanical components of the pilot valves are inserted, the central insert being encapsulated with a plastic material.

    摘要: A braking system for a machine includes a first valve assembly having a first electronically actuated proportional valve, and a second valve assembly having a second electronically actuated proportional valve. The braking system includes a first pressure sensor and a second pressure sensor disposed downstream of the first and second valve assemblies, respectively. The first and second pressure sensors are configured to determine a first pressure and a second pressure of a braking fluid from the first and second valve assembly. The braking system also includes a controller configured to receive a signal indicative of the first pressure and the second pressure of the braking fluid and compare the first pressure and the second pressure. The controller is configured to selectively actuate at least one of the first electronically actuated proportional valve and the second electronically actuated proportional valve to substantially equalize the first pressure and the second pressure.
