Accumulator Installations TRIZ Cases
- Internal Diaphragm Gearbox for Seal-Safe Pressure Equalization
An elastomeric diaphragm and vent chamber equalize thermal pressure in irrigation gearboxes to limit seal failure and oil leakage.
- Pressure Accumulator Burst Disc Triggering Before Overpressure
A pyrotechnic burst disc trigger vents a pressure accumulator before dangerous overpressure, using existing crash sensing for activation.
- Underwater Electrohydraulic Actuator With Balanced Cylinder Chambers
Balanced double-acting cylinder chambers and a vacuum chamber cut hydraulic volume oscillations and pressure compensator stress underwater.
- Screen-Free Pressure Accumulator With Hat-Like Membrane Mounting
A hat-like membrane and integrated flange replace the screen to cut dead volume, weight, and service complexity in rock breaking accumulators.
- Accumulator Vessel Structure for Coaxial Thread and Tool Alignment
Mate-fitted vessel sections align thread and tool engagement portions while reducing welding, part count, and trapped gas volume.
- Multi-Chamber Hydraulic Actuator Control Without Throttling Loss
Quick proportional valves switch discrete chamber pressures to control actuator force while cutting throttling losses and vibration.
- Hydraulic Accumulator Speed Control for Stable Actuator Motion
Actuator speed is limited by accumulator fluid level and pressure to prevent abrupt deceleration and extend controlled hydraulic operation.
- Automatic Ride Control Logic for Low-Gear Hydraulic Lift Arms
Sensor-based ride control uses lift arm angle, speed, and gear state to cushion bucket motion while avoiding pressure spikes during digging.
- Bellows Hydraulic Accumulator With Spacer Pot for Lower-Cost Volume Capacity
A fixed spacer pot adds media volume beside the bellows, enabling fewer folds, lower manufacturing cost, and flexible accumulator sizing.
- Hydraulic Turning Drive With Accumulator-Assisted Braking Force
An accumulator stores regenerated oil during turning deceleration to maintain braking force and reduce main pump load when no other motion occurs.
- Hydraulic Accumulator Shell Joint to Prevent Membrane Damage
A reshaped shell joint and clamping ring secure the membrane during accumulator assembly, preventing weld damage and sealing the chambers.
- Bellows Accumulator Sealing Structure for Uniform Adhesive Bonding
A curved substrate in the sealing member spreads adhesive evenly, preventing detachment and extending accumulator sealing life.
- Hydraulic Reservoir Vortex Chamber for Sealed Oil Deaeration
Tangential vortex flow removes dissolved air from sealed hydraulic oil, while a flexible upper chamber absorbs thermal volume changes.
- Hydraulic Clutch Damping Mechanism for Oil Pressure Judder
A partitioned oil damper stabilizes hydraulic clutch pressure fluctuations to suppress judder vibration and improve vehicle comfort.
- Bellows Accumulator Seal Geometry to Prevent Pinching
A larger seal diameter than the bellows effective diameter prevents seal pinching, protects the bellows, and preserves accumulator sealing.
- Electro-Hydraulic Lift Energy Recovery With Hybrid Storage
Recover lift potential energy during lowering by routing pressurized fluid to a motor-generator and hydraulic storage with fewer valves.
- Bellows Accumulator Cap Structure for Fast Stay Separation
Communication passages in the bellows cap balance pressure quickly, enabling fast stay separation and protecting the seal at low temperatures.
- Bellows Accumulator Geometry for Vibration-Resistant Durability
Sector-based bellows diameters limit vibration amplitude and housing contact, extending hydraulic accumulator service life.
