    Abstract: A valve is proposed for controlling a hydropneumatic device for pressure transmission with a working plunger and a transmitter plunger for pressure transmission, wherein the transmitter plunger is designed to move the working plunger hydraulically on account of a pneumatic actuation with a comparatively high transmission ratio, wherein the valve has a differential plunger arrangement with a first plunger with a first active plunger surface in a first pressure chamber and a second plunger with a second active piston surface in a second pressure chamber, wherein the first plunger is coupled to the second plunger, wherein the first pressure chamber is provided with a first connection for, for example, a pneumatic return-stroke chamber of the working plunger and the second pressure chamber is provided with a second connection for a pneumatic pressure source which differs from the return-stroke chamber, and wherein, in the case of a predefined pressure difference, the valve switches during a working stroke of the working plunger and loads the transmitter plunger with a transmitter pressure. According to the invention, a third plunger with a third active plunger surface is provided, which third plunger is coupled to the second plunger and has a third pressure chamber which can be loaded with a pneumatic pressure source via a third connection, wherein the valve is such that, in the case of a predefined pressure difference between the first and third pressure chambers, the valve switches and supplies any connected transmitter plunger with pressure from the second pressure chamber.

    Abstract: One aspect of the present invention provides a mold assembly for manufacturing concrete blocks that is adapted for use in a concrete block machine. The mold assembly comprises a plurality of liner plates and a gear drive assembly. Each liner plate has a major surface and the liner plates are configured such that the major surfaces form a mold cavity, wherein at least one of the liner plates is moveable. The gear drive assembly is selectively coupled to the at least one moveable liner plate and is configured to move the at least one moveable liner plate in a first direction toward an interior of the mold cavity by applying a force in a second direction different from the first direction, and to move the liner plate in a direction away from the interior of the mold cavity by applying a force in a direction opposite the second direction.
