    摘要： A device for discharging spherical members such as tennis balls, baseballs, etc., comprises a discharge tube through which the spherical members are adapted to be fed, which includes a discharge end and an opposite receiving end having a receiving tube therein for the passage of the spherical members through the receiving tube and into the discharge tube. A fan is arranged to discharge air into a chamber for flow in the annular space around the receiving tube into the discharge tube, and it produces a reduced pressure at the inner end of the receiving tube so that spherical members such as tennis balls, baseballs, etc., which are delivered to the receiving tube are induced to flow into the discharge tube. The apparatus also includes a detent in the form of an elastic rubber sleeve member which arrests a ball after it is first induced to flow through the receiving tube and into the discharge tube toward the discharge end thereof. After the ball is arrested, the pressure within the tube builds up until the arresting force of the detent is overcome and the ball is hurled outwardly from the discharge end of the discharge tube.
