  • Publication number: 20180023553
    Abstract: An oxygen concentrator includes a wobble plate compressor having one or more double-headed pistons and cylinders. A wobble plate of the compressor does not spin as an axle rotates, but orbitally tilts relative to the axle, thereby causing the double-headed pistons to move within the respective cylinders.

  • Publication number: 20160058969
    Abstract: An exhalation valve assembly that controls the pressure of exhaled gas in a ventilation system is described. The exhalation valve assembly includes an actuator module that may be fixed to the ventilation system and a valve module, removable for cleaning or disposal, through which the exhaled gas flows and that controls the pressure and release of the exhaled gas to the environment. Other components may also be incorporated into the assembly including a filter module, a flow meter and a condensate trap.

  • Patent number: 9267503
    Abstract: Rotary systems are described, which can include at least one of compressors and vacuum pumps. Each rotary system includes a corresponding piston that rotates in an orbital motion around a respective eccentric of a shaft in order to either compress fluid or function as a vacuum pump. Multiple rotary systems can be executed on parallel on a single shaft such that these rotary systems are powered by a single motor. Various components of the rotary systems are coated with an abradable coating, which minimizes friction when these components come in contact with each other. The minimized friction minimizes the wear and tear of these components. Each rotary system can be lubricated by only the fluid being processed (for example, compressed or vacuumed) by that rotary system. The use of the fluid being processed for lubrication and the abradable coatings eliminate a need for another lubricant for lubricating the rotary system.
