  • Publication number: 20240118085
    Abstract: A sensor controlled system includes a ramp docking sensor mountable to a vehicle's rear end and configured to fulfill the functions required for assisting docking of a vehicle to a loading ramp. The ramp docking sensor is further configured to determine a vertical distance of the ramp docking sensor relative to a ground level and to determine a vertical distance between the ground level and a loading ramp sill of the loading ramp. In this system, the ramp docking sensor can also be utilized for height-detection of a cargo hold floor with respect to a ground level without requiring specified sensors for height adjustments.

  • Patent number: 11879551
    Abstract: A pressure control valve includes an upper body, a lower body affixed to the upper body, a supply passage in the upper body, a delivery passage in the upper body, an exhaust passage in the lower body and a pivotable member positioned between the supply passage and the delivery passage. The pivotable member has a generally curved body, a first leg, a second leg and a third leg extending from the body. The pivotable member pivots on the second leg and the third leg in response to air pressure in the supply passage being less than the air pressure in the delivery passage. The positioning of the pivotable member restricts air from flowing from the delivery passage to the supply passage, thereby opening a path for the air to pass to the exhaust passage.

  • Patent number: 10059317
    Abstract: A pressure control valve arrangement for controlling fluid pressure in a brake system of a vehicle includes two diaphragm valves and two electromagnetic control valves, activatable by an electronic control device, for the pilot control of the diaphragm valves. The two electromagnetic control valves have a double magnet with two magnet coils and magnet armatures and are actuatable by current being applied to the magnet coils. The housing has at least one pressure medium connection, connected to a service brake valve, for acting with pressure upon and/or relieving the pressure of the pressure control valve arrangement and at least one connection for connecting to a brake cylinder. A plane of symmetry of the mid-axes of the magnet coils of the double magnet is arranged in parallel and offset by the amount of an eccentricity, with respect to a mid-axis of the pressure medium connection.
