    Abstract: PROBLEM TO BE SOLVED: To provide a control valve of a variable displacement compressor capable of increasing discharge capacity by autonomously moving a valve body part in a direction for closing an air supply passage and increasing derived amount of lubricating oil from a crank chamber, even in a state where an electromagnetic actuator part is not energized. SOLUTION: This control valve CV1 is provided with a valve body part urging plate 60 for urging by its deformation a valve body part 48 in a direction to seat on a valve seat 49 when the temperature of the plate reaches a predetermined temperature, in a state where the electromagnetic actuator part 52 is not energized and the valve body part 48 is held at a position separated from the valve seat 49 by the urging force of a valve opening spring 57. The urging force of the valve body part urging plate 60 when the temperature reaches the predetermined temperature is set to be larger than the urging force of the valve opening spring 57 in a state where the electromagnetic actuator part 52 is not energized.

    Abstract: A slurry injection system has a plurality of slurry valves fluidically coupled to first and second elongated tanks. In the first state, the slurry valves communicate high pressure slurry from the second volume to a site and communicate low pressure slurry to the fourth volume. In the second state, the slurry valves communicate low pressure slurry to the second volume and high pressure slurry from the fourth volume to the slurry injection site and in the intermediate state communicating high pressure slurry simultaneously from the first elongated tank and the second elongated tank to the slurry injection site. In the first state clear fluid valves fluidically communicate high pressure clear fluid to the first volume and low pressure clear fluid from the third volume and, in a second state, communicate low pressure clear fluid from the first volume and high pressure clear fluid to the third volume.

    Abstract: A power end frame assembly for a reciprocating pump that includes a first and second end plate segment each including annular bearing support surfaces configured to support a crankshaft bearing assembly. At least one middle plate segment is disposed between the first and second end plate segments and includes an annular bearing support surface configured to support a crankshaft bearing assembly. The annular bearing support surfaces of the first and second end plate segments and the at least one middle plate segment each have a diameter and are coaxially aligned. The diameter of at least one of the first and second end plate segments is different from the diameter of the at least one middle plate segment to facilitate insertion and removal of the crankshaft bearing assembly from the power end frame assembly.

    Abstract: An electroproportionally controlled differential pressure valve cartridge includes actuation and tank ports on an outer circumference, and a pump port on a face-side. A spring preloads a piston into a position that relieves pressure from the actuation port to the tank port. A current increase through an electromagnet opposite the pump port and a pressure increase at the pump port counter the spring to open a connection from the pump port to the actuation port. A concentric opening extends from the pump port to a first piston surface. A duct extends from the first piston surface to a pump chamber. A further duct extends from the pump port to a spring chamber between the pump chamber and electromagnet. In the spring chamber, pressure over a second piston surface counters pressure over the first piston surface.

    Abstract: Load sharing is achieved in a multiple compressor system by a program in a computer which sends signals to, and receives data from, a microcontroller located at each compressor. One compressor, designated as the lead compressor, furnishes its operating parameters, via the computer, to all the other, lag, compressors. The operating parameters include inlet valve position and bypass valve position of each compressor and the microcontroller controls the actuatation of both valves. When system demand decreases, compressors are gradually unloaded, and then stopped to go off-line. When system demands increase, compressors are first started, and then gradually loaded before going on-line. Compressors go both on-line and off-line subject to certain time delays so that compressors are gradually added to, or shed from, the load. To equalize running time, all compressors in the system may undergo a periodic rotation and compressors go off-line in reverse order that they came on-line.
