Abstract: An interlocking isolation valve assembly is described. The valve assembly is adapted to be connected to a hydraulic circuit, and it includes: a first isolation valve and a second isolation valve and an interlock means wherein the second valve is inhibited from moving to a return position if the first valve is at least partially in an open position, and the first valve is inhibited from moving to the open position if the second valve is in the return position. There is also described a method for venting a high pressure hydraulic machine such as for example a longwall roof support, in which the high pressure circuit is vented to the return circuit. Another aspect of the invention is a high pressure hydraulic machine which in one form is a longwall roof support, which is removed from a closed loop circuit by venting a high pressure circuit to a return circuit.

Abstract: Differential pressure generator (100) includes a stacked pair of opposed novel gravity transducers of the inverted-cup falling-cylinder type. First enclosure (21) contains a first gravity transducer (23) and second enclosure (31) contains a second gravity transducer (33). First gravity transducer (23) includes first cylinder (24), and first piston (25). The first cylinder is mounted for gravity-driven, viscosity-limited motion with respect to the first piston to generate a first pressure difference. The second gravity transducer includes a second cylinder and a second piston. The second cylinder is mounted for gravity-driven, viscosity-limited motion with respect to the second piston to generate a second pressure difference. The first cylinder has a displacement volume that is equal to the displacement volume of the second cylinder, and the first cylinder is heavier than the second cylinder. The first pressure difference and the second pressure difference are summed in opposition to produce a reference differential pressure.
