  • Patent number: 9206802
    Abstract: A rotatable drive shaft in the swash pump or turbine for liquids is supported by one bearing at each end. An integrated motor or dynamo uses the same two bearings. The compound first bearing supports a slanted section of the drive shaft placed inside the inner swash sphere, and transfers rotational power to the attached nutatable swash plate. The second bearing confines rotation of the drive shaft in a defined axis. Either one of the bearings is made to prevent axial movement of the drive shaft, preventing swash pump misalignment. A resilient drive, and an immersed pump are described.

  • Patent number: 8770237
    Abstract: A method of operating a vapor recovery system that recovers vapors expelled from a vehicle during refueling at a fuel dispensing point and returns the vapors to an underground storage tank through a vapor flow path that is in fluid communication with an air to liquid regulator valve and a vapor pump. The method includes dispensing fuel into the vehicle through the fuel dispensing point, regulating an amount of vapor that is recovered through the fuel dispensing point with the air to liquid regulator valve in proportion to the fuel dispensed into the vehicle, detecting a parameter of the vapor recovery system, and maintaining a substantially constant pressure level in a first portion of the vapor return path that is disposed between the vapor pump and the air to liquid regulator valve.
