(14.) In a feed mechanism for feeding liquid fuel in explosive motors, the combination with an oil-cup of a force-pump for feeding and a pipe for supplying fuel to the oil-cup, a feed-pipe for feeding the fuel from the cup to the motor, the inlet to which feed-pipe is lower than the fuel-inlet to the cup, a valve for closing said pipe, an overflow-pipe the main inlet of which is higher than the fuel-inlet to the cup, and which has an inlet-orifice which is lower than said main inlet to said pipe, but higher than the inlet from the cup to the feed-pipe, and a device which connects the piston of the pump with an adjacent valve-stem of the motor, as described. (15.) In a feed mechanism for feeding liquid fuel in explosive motors, the combination with an oil-cup, and means for supplying liquid fuel thereto, of an outlet feed-pipe the inlet to which from the cup is lower than the inlet for the fuel into the cup, and which is extended into the air-supply passage of the motor, and has an outlet opening into said passage, a valve and valve-seat for controlling the feed of the fuel outward through said opening, an overflow-pipe the inlet to which is higher than the outlet from the cup to the feed-pipe, and which has a second inlet-orifice which is higher than the opening of the feed-pipe into the air-supply passage, as described.
