Hydraulic Valve
What make’s the hydraulic release sound when a bus stops, it sounds like a blow off valve.?
I need to know the exact name of this mechanical part.
Those are actually air brakes, which is why it sounds like a blow off valve. Basically a fully pressurized system opens the brakes allowing the wheels to role. The foot valve, as the name implies is attached to the brake peddle. As you press the brake peddle the foot valve is opened allowing air to escape and the brakes to engage. When the bus stops the driver likely locks the brakes but opening the safety bypass valve which keeps the brakes from releasing until he/she releases the safety. Once the safety is released the system can recharge, release the brakes and the vehicle can move again. Hope this helps.

Simrad Hld Mk2 Hydraulic Linear Drive Units Hld2000 Lenear Long, Dual $3599.99 Simrad Hld Mk2 Hydraulic Linear Drive Units Hld2000 Lenear Long, Dual . HLD350 MK2 and HLD2000 MK2 are hydraulic linear drives designed for boats with mechanical steering systems such as wire and cable steering (Edson, Whitlock, Teleflex). Linear drives are the most preferred on sailboats, attached to the quadrant or tiller, supplying direct control, avoiding slack in wires or cables. The HLD includes a reversible hydraulic pump, a balanced hydraulic cylinder, bypass valve and oil tank. Because of the direct connection to the rudder, the hydraulic linear drive can be used even if the hand steering should fail, an important safety factor. The bypass allows you to use the helm with little back-drive force when the autopilot is switched off. Split version has the pump separated from the ram and interconnected with 3′ hoses, making the installation more convenient when space becomes a problem. Dual ram version for larger sailboats. |
