  • Patent number: 10794513
    Abstract: Aspects of the disclosure relate to an overload protection valve for automatic release of a load. The valve may include an outer housing having an end wall, a cam, and inner slide, and an overload spring. The inner slide may include a side wall, a shelf area, an internal barrier, an inlet and an outlet. Each of the inlet and outlet may include an opening through the side wall, and the inlet and the outlet may be separated by the internal barrier. The overload spring may be arranged between the end wall and the shelf area, and may define a load on the valve which will cause the valve to open. The cam may be configured such that when the valve is closed, the defined load will cause the cam to rotate thereby allowing the openings of the inlet and outlet to be in fluid communication and open the valve.

  • Patent number: 10525950
    Abstract: A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. The enhanced braking mode strategy is used unless trailer capability information reported by one or more the trailers fails to match against expected trailer capability information.

  • Patent number: 10473228
    Abstract: A solenoid valve comprises first, second, and third ports. The solenoid valve further comprises an armature movable between a first position in which fluid flow from the second port to the third port is blocked and fluid flow from the first port to the third port is unblocked and a second position in which fluid flow from the second port to the third port is unblocked and fluid flow from the first port to the third port is blocked. The fluid flow in the second position is blocked until fluid pressure at the first port exceeds fluid pressure at the third port by a predetermined amount to thereby provide check valve functionality. The check valve functionality is integral to the armature. The solenoid valve also comprises an energizeable solenoid that, when energized, moves the armature from the first position to the second position.

    Abstract: An air brake relay valve includes an air guide unit having a movable set, a drive unit having a motor and a worm shaft, and a cam unit having a transmission member and a driven member. During a brake action, the motor rotates the worm shaft to rotate the transmission member so as to push the driven member downward to thereby move the movable set to a communicating position where a first valve opening and a second valve opening fluidly communicate with each other. When the brake action is released, the motor rotates reversely so that the driven member is moved upward and that the movable set moves, without being applied with additional force, to a non-communicating position where the first and second valve openings do not fluidly communicate.

  • Publication number: 20140345731
    Abstract: A bistable fluid valve is characterized by two valve chambers which are arranged adjacent to one another and are closed off with respect to one another by a partition and each have an inlet opening and an outlet opening situated opposite one another, by an S-shaped elastic strip element which extends through both valve chambers, is articulatedly mounted in the region of the partition and can assume two positions in which it sealingly closes off either one or the other outlet opening, and also by an actuation element which is fastened to the strip element and by means of which the strip element can be switched between the two positions. The fluid valve according to the invention comprises only a single movable component of very low mass, which can thus operate in a fast-reacting manner.

  • Patent number: 8869834
    Abstract: A pneumatic control device includes a direction control rod, which is connected to a power switch device for activating and shutting off the power switch device. When the direction control rod is in the positive position, the first direction control valve is activated to drive a pneumatic power device. The pneumatic power device drives a hydraulic power tool to move in positive direction. The first direction control valve is shut-off and the second direction control valve is activated when the direction control rod is moved to the opposite position. The activated second direction control valve drives the pneumatic power device; the pneumatic power device drives the hydraulic power tool to move in opposite direction. When the direction control rod is moved to the opposite position, the activated power switch device is relieved and automatically shut off to stop supplying power to the hydraulic power tool.
