Valve Arrangements TRIZ Cases
- Pinless Tappet Anti-Rotation Lock Bar Mechanism
A lock bar engages a flat portion on the tappet casing to prevent rotation during linear oscillation.
- Switching Roller Finger Follower T-Shaped Inner Arm Stiffness
A switching roller finger follower uses a T-shaped inner arm assembly to pivot within a forked outer arm for selective locking.
- Follower Mechanism Non-Rotatable Fixation Without Heat Treatment
Inner cup alignment tab prevents rotation while outer cup avoids distortion from heat treatment, simplifying assembly.
- Valve Timing Adjuster Knock Pin Alignment
Knock pin abuts inner walls of sprocket and housing holes to prevent positional deviation during engine start.
- Integrated Liquid Gas Connector for Tank Misconnection Prevention
Merges separate liquid delivery and gas feed plugs into one unit to eliminate labor-intensive individual installations.
- Microfluidic Valve Section With Expanding Cross-Section
An expanding channel cross-section prevents soap film formation and residual retention, enabling reliable venting for multi-use biochemical assays.
- Cylinder Equalization via Exhaust Back Pressure Correlation
A control unit correlates exhaust gas back pressure with camshaft position to adjust cylinder-specific charge quantities.
- Roof Hydrant Mount with EPDM Sealing Boot
Segmented flange and boot components resolve structural rigidity versus leak resistance contradictions in roof-mounted hydrants.
- Rocker Arm Mechanism for Engine Braking
A rocker arm mechanism adjusts exhaust valve timing to decompress cylinders before the compression stroke.
- Exhaust Pipe Clogging Detection via Pressure Feedback
Pressure feedback triggers targeted cleaning only when clogging occurs, reducing liquid waste.
- Hydraulic Lash Adjustment Capsule for Engine Brake
Hydraulic capsule assembly adjusts plunger position via fluid pressure to eliminate mechanical lash adjustment complexity.
- Switching Rocker Arm With Cantilevered Rollers
A switching rocker arm uses cantilevered rollers and dual lost motion springs to enable variable valve lift profiles.
- Load Lock Elevation Shaft Vacuum Evacuation
A load lock device uses vertically extended elevation shaft members to support a holding unit while enabling vacuum evacuation through the container opening.
