  • Patent number: 8827657
    Abstract: A concrete pump system/method configured to provide substantially constant flow of concrete or cement material is disclosed. The system integrates a trapezoidal cutting ring and spectacle plate in conjunction with lofted transitional interfaces to the hydraulic pump cylinder rams and output ejection port to ensure that pressurized discharge concrete material is not allowed to be relaxed nor backflow into the material sourcing hopper. The trapezoidal cutting ring is configured to completely seal off the trapezoidal spectacle ports as it smoothly transitions between the hydraulic pump input ports during cycle changes thus generating a more uniform output flow of concrete while eliminating hopper backflow and hydraulic fluid shock. A control system is configured to coordinate operation of the hydraulic pump cylinder rams and cutting ring to ensure that output ejection port pressure and material flow is maintained at a relatively constant level throughout all portions of the pumping cycle.

  • Patent number: 6058974
    Abstract: The invention relates to a valve for changing the flow direction of a fluid in conduits, which conduct the fluid to and from, respectively, a heat exchanger. Heat exchangers used in systems where the cooling water is taken from natural streams, river water, sea water etc often have problems with clogging. A method of keeping the heat exchanger clean is to regularly backflush it, i e to reverse the flow direction for example a few times every day, so that silt and particles, which have got stuck in the inlet region of the heat exchanger, are flushed out the same way as they entered.The valve according to the invention comprises a cylindrical casing and a valve body (18) enclosed therein. The conduits, which conduct the fluid to and from, respectively, said heat exchanger, are connected to two diametrically arranged connection tubes in the respective end plate on the casing, and by rotation of the valve body substantially 90.degree.

  • Patent number: 5966847
    Abstract: A portable excavator having a tube to point a supersonic gas stream at a buried object. The excavator includes a movable member disposed within the conduit to pulse gas passing through the conduit and a supersonic gas nozzle at the exit of the conduit. Compressed gas delivered to the conduit exits the nozzle in a pulsed manner at two to three Hz. The movable member includes a piston which blocks gas from flowing through the conduit by the biasing force of a spring. When the force from the pressure differential across the piston exceeds the biasing force, the piston moves and allows gas to flow through the conduit until the force from the pressure differential across the piston is less than the biasing force.

  • Patent number: 5857490
    Abstract: A pump valve assembly includes a pair of pistons containing cylinder bores opening to a front wall for conveying a concrete mixture from a feed chamber to a delivery tube. A pivotal S-bend tube establishes fluid communication between two valve body wear rings and the delivery tube to cause a translational movement of the input port to the valve assembly between two operative positions in which the input port is in register with the wear rings, the S-bend tube also being engaged with a wear ring. During use, compression of the valve assembly against a positive displacement pump is achieved solely at the front wall of the assembly, with the delivery tube at the rear wall providing only alignment and support, thereby enabling rapid disassembly and access to the valve body and S-bend wear rings.
