Accumulator Installations TRIZ Cases

A dual-piston assembly stabilizes closed-loop coolant pressure and injects reserve fluid after pressure drops, reducing cavitation and maintenance.

A hydraulic accumulator captures motoring energy in a single-rod EHA and reuses it to assist pumping, cutting input power and heat loss.

A hat-shaped elastic membrane replaces internal screens to cut dead volume, weight, and complexity in rock breaker pressure energy storage.

Stored swing-motor oil is reused during acceleration to recover deceleration energy and prevent cavitation in construction machine hydraulics.

A portable HPU skid shares hydraulic pumps across valve actuation and grease delivery, cutting frac pad equipment and line count.

Three dedicated main pumps and energy recovery reduce hydraulic pressure mismatch losses during simultaneous boom, swing, arm, and bucket operation.

A single engine and gearbox layout drives multiple pumps for up to eight pipe-cleaning passes while reducing trailer space and crew needs.

A compact electro-hydraulic rail tilting actuator uses local pump and valve integration to avoid jamming, cut space needs, and center by gravity.

A locally thickened weld zone and tapered shell wall suppress weld breakage under pressure while keeping the accumulator lighter.

A high-density compensation liquid raises hydrostatic pressure, letting compressed gas storage reach higher energy density at shallower depths.

A hybrid lead screw and hydraulic chamber design delivers precise linear motion, high load support, and lower maintenance in harsh environments.

Radar-based position sensing tracks the separator in a hydraulic accumulator despite moisture, contamination, heat streaks, and tight space.

Uses machine motion to drive a pump and pressure storage, enabling pneumatic grippers and cleaning without external compressed air.

Localized shell thickening at the weld and a tapered transition reduce stress concentration, prevent breakage, and avoid excess accumulator weight.

Gas-infused closed-cell tubing replaces gas bladders in suction stabilizers to absorb pressure pulsations without gas replenishment.

An anti-cavitation line and self-priming path keep fluid flowing to the assist motor inlet, preventing cavitation and preserving energy recovery.

A detachable base body and annular seal let the metal bellows be removed for maintenance while keeping the accumulator housing leak-tight.

Sectorized bellows ridge diameters and a damping ring limit housing contact under vibration, extending accumulator bellows life.

A dual-material securing device lets titanium housing and a stainless steel bellows be joined for lightweight, high-pressure accumulator design.

A dual-gas chamber accumulator uses separate pre-charge pressures and spring dampening to smooth piston stops and limit pressure spikes.

Dual gas chambers and a cushioned second piston absorb wide oil-pressure variations, reducing abrupt stops, spikes, and flow instability.

A threaded top cover and standardized anti-extrusion bladder cut dampener repair time by enabling in-place bladder replacement.

A reciprocating chamber with high-, low-, and tank-pressure sections enables compact hydraulic energy recuperation without separate low-pressure accumulators.

Continuous pump control charges the hydraulic accumulator before each cycle, cutting leakage, noise, and pump wear in molding machines.

A stationary regenerator stores compression heat and releases it on discharge, improving plunger accumulator efficiency while lowering machining cost.

A portable HPU skid combines hydraulic pumps, accumulators, and a grease pump to cut frac pad lines, idle equipment, and space use.

Closed-cell elastomer tubes hold infused gas to damp pump pulsations and cavitation without bladder recharging, including retrofit use.

Ported dispersion tubing keeps hydraulic fluid flowing to the seawater chamber, preventing bladder collapse and vacuum during subsea depth compensation.

Gearboxes let one engine drive multiple low-mounted pumps, enabling up to eight simultaneous pipe-cleaning passes with less trailer space and crew.

A stepped guide sleeve and retaining fin stabilize diaphragm bellows, prevent canting, and reduce weld seam wear without limiting axial travel.

Tangential vortex flow separates air from hydraulic oil in a closed reservoir, limiting re-dissolution, moisture uptake, and thermal volume issues.

A boost cylinder and energy storage device raise nominal hydraulic pressure for intermittent peak demand without oversized pumps or relief losses.
