Valve Drives TRIZ Cases
- Dual Swash-Plate Camshaft Actuator for Rapid Timing Adjustment
A dual swash-plate actuator rotates coaxial camshaft shafts to enable rapid timing adjustments.
- Switchable Valve Train for Engine Braking
A switchable valve train uses a mode-selecting rocker arm to transmit camshaft inputs.
- Camshaft Adjuster Clamping Unit Reduces Torque
Clamping unit generates friction between camshaft and rotor using axial prestressing force from a central screw.
- Sliding Cam System Axial Displacement Boundary Portion
Identical cam boundary sections allow axial displacement beyond base circles, reducing inertial forces and extending service life during high-speed switching.
- Variable Valve Lift Apparatus for V-Type Engine Torque Stability
An offset rotation center creates symmetric valve profiles in V-type engines, minimizing torque fluctuation without adding device complexity.
- Sliding Cam Valve Drive Actuator with Intermediary Piece
An intermediary sliding piece reduces surface pressure and weight in multi-stage valve drives by distributing contact forces.
- Variable Valve Duration Cam Mechanism for Engine Efficiency
A cam mechanism adjusts valve opening duration by varying the phase angle between camshaft and cam slots.
- Asymmetric Latch Pin Assembly for Rocker Arm Orientation
Non-circular latch pin and retainer cross-sections eliminate complex rotational orientation requirements, reducing manufacturing costs.
- Rotary Pressure Amplifier With Radial Wings
A pressure amplifier uses a rotor with radial wings to compress fluid volume, eliminating linear stroke space constraints.
