摘要： Disclosed is a power conversion system for controlling the flow of a hydraulic power signal between a power source and a hydraulic actuator having first and second ports. The power conversion system includes a control valve that is configured to selectively expose each of the first and second ports to one of the power source and a low pressure reservoir. An enabling valve having a disabled position, a first enabled position, and a second enabled position receives an input from the control valve and provides an output to the hydraulic actuator.

摘要： A hydraulic tubing clamp is made of a resilient plastic or polyamide material with a mounting hole for accepting a fastener to attach the tubing clamp to a mounting surface of a product, such as a boom arm of a front end loader. Recessed grooves or tubing seats are formed with part cylindrical portions for accepting hydraulic tubes. The recessed grooves are accessible for snap fitting tubes into place through an opening that is more narrow than the widest parts of the recess. Once snap-fitted into place, the tubes are retained in the tubing clamp as a subassembly without the use of latches or other clamping devices. The preassembled bundle of tubes held by the clamp can be assembled on the loader or other product with greater ease and efficiency than trying to manually hold the tubes in place and then fasten or clamp the tubes to the product.
