  • Patent number: 12025122
    Abstract: The carbon free compressor pump system is a device that utilizes several pistons in a hydraulic or power press manner to compress gas or pump fluids. The device utilizes mechanical advantage of a pulley on the upstroke and uses a clutch device to utilize the gravitational force on the downstroke. In order to accomplish this the device includes a base that allows the compression process to take place and ensure there is only vertical movement. Further, the weight block ensures the system can utilize gravitational force on the downstroke. Further, the plurality of outtakes allows for the gas or fluids to flow out of the system once compressed or pumped. Furthermore, the conical tank takes the compressed gas or pumped fluid and further compresses the gas, increasing the pressure without moving parts. Thus, the device operates on carbon free electricity to compress gas and pump fluids.

  • Patent number: 11994139
    Abstract: An inflatable product includes an integrated axial-flow pump which produces a high rate of inflation. The pump includes a cover mounted to a body of the pump and selectively configurable between open and closed positions. In the open position, air is allowed to flow between the inflatable chamber and the ambient air through the pump body. When the cover is closed, the air chamber of the inflatable product is sealed with respect to the ambient air such that air is retained within the inflatable chamber when inflated. A power switch is positioned to be deactivated by the cover when the cover is mounted to the body of the pump, such that replacement of the cover during inflation or deflation of the inflatable product automatically deactivates the pump.
