Abstract: A latching mechanism for a cab which is tiltably mounted to the chassis of a vehicle. The cab is normally disposed over the engine of the vehicle in a first or lowered position and is pivotally attached to the chassis at its forward end for movement through 90.degree. to a second or raised position. The latching mechanism securely locks the cab in the lowered position and includes interengaging latching elements attached to the underside of the cab and to the chassis of the vehicle. The receiving means includes a ball detent arrangement actuated by means of a hydraulically powered cam sleeve. The ball detents move radially between a first or unlocked position and a second and locked position. When in the locked position, the detents engage shoulder portions on one latching element to securely lock the cab to the chassis.

Abstract: A valve section which establishes priority flow in a valve assembly having a plurality of directional control open-center valves each for controlling flow between an associated hydraulic motor and a common power passage from a single source of motive fluid, wherein flow to one of the motors is afforded priority during simultaneous operation of it and another motor. The associated valve section of the priority motor having a conventional load check valve opened by pressure in the common power passage while the load check of the non-priority valve section is opened by pilot pressure in its open-center passage.
