Application And Release Valves TRIZ Cases

Vehicle-speed-based control coordinates service and parking brake force to prevent wheel locking and maintain stability during parking braking.

Electronic control links separate brake levers to rear caliper oil pressure, reducing front-rear wheel speed differences during braking.

An asymmetric groove and insertion wall contain sealing material, improving housing airtightness without enlarging the motorcycle brake pressure control unit.

A localized valve chamber and moving spool separate service and parking brake control to prevent dual braking without slowing pressure response.

A pressure-equalizing piston limits rail brake cylinder pressure and vents it automatically when supply pressure is removed, reducing leaks and valve complexity.

Integrated clamping portions and airflow slits simplify spring brake valve retention, improve centering, and prevent brake damage during compounding.

Separate cover portions for each valve cavity improve alignment and sealing in ABS brake modulators while reducing leakage risk and cost.

Plastic cover portions and a relay valve cover plate improve sealing and self-centering alignment while cutting brake modulator assembly cost.

A 3/3-way valve lets the parking brake circuit support service braking during pneumatic failure while preserving ABS function.

Dual microcontrollers and AI-controlled solenoid valves regulate brake pressure to deliver repeatable stopping distances without mechanical recalibration.

A collar-constrained sealing member keeps the control pressure line sealed in tight brake valve spaces despite corrosion and deformation.

An auxiliary air passage opens only when line pressure drops and the parking brake switch is OFF, preventing unintended brake engagement.

Automatic brake control uses connection, parking brake, and speed signals to stop pull-away from connected infrastructure without low-speed false positives.

Pressure-sensor feedback triggers brake valves during filling, removing adapters and data links while speeding bubble-free secondary circuit filling.

A spring-loaded piston vent valve releases residual brake pressure quickly after braking, helping prevent rail brake jamming, wear, and noise.

Elastic coupling elements disconnect trailer brake joints under excessive tension to prevent hose breakage, fluid spillage, and downtime.

A self-centering relay valve cover plate and segmented cover portions reduce leakage, relax alignment tolerances, and cut brake modulator cost.

When one piston stroke cannot meet extreme braking demand, this case uses cutoff, refill, and re-pressurization to sustain brake pressure in a compact module.

Fluid pressure seals an intermediate element in a relay valve, reducing seal wear, leakage risk, vibration, and brake noise.

Separate valve-cavity covers and a relay valve cover plate shorten the tolerance chain, improving ABS modulator sealing and assembly cost.

A pull-out visual indicator adds clear engaged-position feedback to a hand brake valve when audible or tactile cues are unreliable.

A single brake line handles service and parking brake actuation, cutting line count while keeping parking force without continuous pressure.

A deformable insert seals the supply path during exhaust, improving pneumatic ABS valve release reliability without extra throttle parts.

An inlet in the pump housing guides brake fluid axially into the outlet valve, cutting redirection losses and simplifying brake pressure control.

A throttle-linked pneumatic brake valve switches between bistable and relay modes to prevent parking brake force overshoot during power loss.

Fluid pressure seals the relay valve intermediate element against its stop, cutting wear, leaks, and noise without extra seals.

Circumferential clamping slits replace circlip-and-plate valve retention to simplify assembly, improve airflow, and prevent brake force damage.

A double-stroke piston pump with 3/2-way valves improves brake pressure control, circuit redundancy, and fail-safe operation at lower valve cost.

A pressure compensation piston limits rail brake pressure and opens venting on shut-off, protecting brake mechanics while reducing leaks and maintenance.

Below a deceleration threshold, one axle brake circuit is selected for finer pressure steps, enabling smoother braking and lower wear.

Wheel-blocking detection lets the ECU reduce or stop gradual parking brake actuation in motion, improving commercial vehicle stability.

Parking brake signals drive electropneumatic valve switching to add trailer parking and auxiliary braking with compact retrofit integration.

A telescopic snap-fit piston with flexible arms secures tubular assembly while enabling infinitely variable compressed air control in trailer braking.

A solenoid-controlled common valve unit replaces fixed pneumatic settings, cutting assembly complexity while adapting pressure limits in real time.

A combined BCM and quick service valve uses a diaphragm and shared seats to cut pressure offset and maintain brake cylinder pressure accurately.

Segmenting the TCS ESC modulator into specialized solenoid, changeover, and pneumatic relay valves reduces overall system volume and manufacturing costs.

Integrating the valve seat and intermediate wall into a single plastic component eliminates piston oscillation and enhances dynamic control behavior.

A filter module removes wheel rotational frequency oscillations from brake fluid pressure signals to stabilize control accuracy.
