摘要：
A characteristic feature of the invention lies in that a container for each liquid component, incorporated in a sand machine, is provided with an actuator intended for effecting forcible opening of the container spring-loaded valve, a device for controlling this actuator, and an eccentric mounted on the shaft of a drive for actuating feeders and acting on the control device; each proportioner for a fluid component is provided with spring-loaded diaphragms, of which one is adapted to control a feeder for loose components and the other, to close the feeder outlet. The connection between the feeders is effected by an intermediary member connected with the spring-loaded diaphragm and brought in contact with a cam mounted on the shaft of the drive for feeders and set at an angle of 2 to 15 deg. relative to the eccentric.
