Latest Patents
Rotharmel's latest patents include a Remote Controlled Vehicle Damper and a Dampener Valving Control Mechanism. The Remote Controlled Vehicle Damper features a variable damping shock absorber with a two-wire electrical lead extending into the piston rod. This design allows electrical energy to drive a motor that rotates in alternating directions, depending on the internal switch's setting. The motor operates an internal rotatable valve, which regulates fluid flow as the piston moves within the shock absorber. The Dampener Valving Control Mechanism is activated by the depression of a pin on the upper end of the shock absorber piston. This action engages a spring-loaded ratchet drive, allowing the valve to slide between open and blocking positions, effectively controlling fluid flow.
