摘要:
A play feature for a pinball game permits the storage of a number of game balls and release of the balls at high speed and in quick succession back onto the playfield for multiple ball play. A rotor element having a plurality of vertical vanes is disposed within a circular housing having a conical lip. The base and vanes of the rotor, together with the conical lip, define receptacles for receiving game balls. When a predetermined rotor speed is reached, the balls travel upwards on the conical lip and outward against an outer wall of the housing. The stored balls are conveyed successively to a discharge channel where they return to the play field at high speed.
