Abstract
A biased dual tip seal arrangement for the rotor (106) of a rotary engine (102). The dual tip seals (100-T, 100-L) are located on opposite corners of the tip (130) of a planetary rotor (106). The rotor (106) orbits within a cutout (126) in a main rotor (108). The seals (100-T, 100-L) are biased away from the corners to make sealing contact with the sealing surfaces of the asymmetrical lobe (112) and the cutout (126) of the main rotor (108). Biasing is implemented with springs (1202, 1302, 1412) and with conduits (1006) that pressurize the area under the seals (100-T, 100-L). An asymmetrical lobe (112′) includes a transition zone (802) on the surface of the lobe (112). In the transition zone (802), at least one seal (100-T, 100-L) on the tip (130) maintains contact with the surface (112′) while alternating contact from one seal (100-T, 100-L) to the other.
