SCROLL PUMP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240018960 titled 'SCROLL PUMP
Simplified Explanation
The abstract describes a scroll pump that consists of an inlet, an outlet, a fixed scroll, and an orbiting scroll. The fixed and orbiting scrolls are intermeshed with each other, creating a space in between. The pump also includes a biasing apparatus to apply pressure on the orbiting scroll against the fixed scroll. A fluid recirculation channel extends from the space to the inlet through either the fixed or orbiting scroll. A fluid recirculation valve is positioned in the fluid recirculation channel, allowing or blocking the flow of fluid from the space to the inlet. The valve switches from a closed state to an open state when the pressure difference across it reaches or exceeds a certain threshold.
- The patent is for a scroll pump design with a fixed and orbiting scroll that creates a space for fluid flow.
- A biasing apparatus is included to ensure proper contact between the scrolls.
- A fluid recirculation channel allows fluid to flow from the space to the inlet.
- A fluid recirculation valve controls the flow of fluid through the channel.
- The valve opens when the pressure difference reaches or exceeds a specific threshold.
Potential Applications:
- Vacuum systems
- HVAC systems
- Industrial processes requiring fluid pumping
- Medical equipment
Problems Solved:
- Efficient fluid pumping with reduced leakage
- Improved control over fluid flow
- Enhanced reliability and performance of scroll pumps
Benefits:
- Higher efficiency and energy savings
- Reduced maintenance and downtime
- Improved system performance and reliability
Original Abstract Submitted
a scroll pump includes an inlet and an outlet, a fixed scroll and an orbiting scroll intermeshed with each other, wherein the fixed scroll and orbiting scroll define a space therebetween. the scroll pump further includes a biasing apparatus configured to bias the orbiting scroll against the fixed scroll, a fluid recirculation channel which extends from the space to the inlet through either the fixed scroll or the orbiting scroll, and a fluid recirculation valve disposed in the fluid recirculation channel. the fluid recirculation valve is configured to permit flow of fluid from the space to the inlet through the fluid recirculation channel or to block flow of fluid through the fluid recirculation channel. the fluid recirculation valve is configured to switch from a closed state to an open state when a pressure differential across the fluid recirculation valve is equal to or exceeds a certain threshold value.
