- Swing Vane Pump Side-Cover Structure for Fretting Corrosion
Matched side-cover cylindrical portions and a low-pressure oil passage limit junction distortion and prevent fretting corrosion in swing vane pumps.
- Oscillating Vane Pump Actuator Structure for Fretting Corrosion Prevention
A low-pressure passage and shape-matched side covers limit junction distortion and prevent fretting corrosion in vane pump actuators.
- Magnetic Nutating Wobble Plate Drive for Low-Shear Blood Pumping
A rotating magnetic field drives a constrained wobble plate to pump blood with far lower shear and no shaft seals or artificial valves.
- Fiber-Reinforced Screw Rotor Assembly for Lightweight Torque Transfer
Shaft locking elements in a fiber-reinforced polymer screw rotor prevent axial and rotational slip while cutting weight, waste, and finishing steps.
- Hydraulic Piston Insert Structure for Dead Volume Reduction
An insert extending beyond the piston hollow cuts dead volume from water compressibility while stabilizing position and allowing cooling flow.
- Fluoropolymer Compressor Cup Seal for Low-Wear Sealing
Angled fluoropolymer cup seals with carbon, graphite, or MoS2 fillers cut compressor seal wear and extend fluid-tight service life.
- Hydraulic Piston Insert Mounting With Pliable Rings for Low-Cost Efficiency
Pliable rings secure a hollow-piston insert against deformation and wear while allowing cooling fluid flow and lower manufacturing cost.
- Oval-Gear Piston Engine Layout for Balanced Motion Conversion
A lever-driven oval gear layout balances rotating mass and cuts lateral piston forces for smoother, lower-cost rotary-to-linear conversion.
- Multi-Chamber MVC Compressor for Independent Stage Compression Control
Independent dual-action compression chambers let each MVC stage tune flow rate and compression ratio, cutting entropy, energy use, and heat-exchanger area.
- Reciprocating-Piston Gas Expansion With Rotary Slide Valve Timing
Timed rotary slide valve closure compresses residual gas near top dead center, cutting pressure differential and wear in piston gas expansion.
- Hydraulic Circuit Valve Control for Multi-Actuator Flow Demand
Discrete demand signals control chamber valves to match multi-actuator hydraulic flow, cutting energy waste and preventing engine droop.
- Hydraulic Circuit Control With Variable Chamber Displacement
Active low-pressure valve control varies working chamber displacement to match actuator demand, improving hydraulic energy use and stability.
- Dual-Inlet Rotary Vane Vacuum Pump for Multi-Chamber Evacuation
A dual-inlet rotary vane pump evacuates two vacuum chambers with one outlet, cutting pump-down time, space, and maintenance cost.
