APPARATUS FOR ADMITTING HARDENABLE MATERIAL INTO THE DIES OF MOLDING MACHINES ABSTRACT A valve which serves to admit hardenable metallic, plastic or other material into the die of a molding machine has a housing with a centrally located passage for a reciprocable needle-like valving element, an inlet for hardenable material at one side and adjacent one end of the passage, an outlet which is coaxial with the other end of the passage, an eccentric chamber disposed at the one side of the passage and communicating with the inlet, and an elongated gap which establishes communication between the chamber and the passage. The valving element is movable between an extended position in which it seals the gap from the outlet and a retracted position in which the gap admits hardenable material into the passage so that the admitted material can flow toward and through the outlet. The housing surrounds the valving element in the region of the gap along an arc of more than 180°.
