Abstract: The Application describes a throttle and a method for controlling a fluid flow via a throttle . The throttle includes an inlet (618) in communication with a pressurized gas source, an outlet (610) including a selected output orifice (612), and an orifice sleeve (606) including a plurality of output orifices (612a, 612b, 612c, 612d) from which a selected output orifice (612) may be selected by rotating the orifice sleeve (606). The throttle may further include a piston (604) movable across a surface area of the selected output orifice (612), and a motor operable to move the piston (604) across the surface area of the selected output orifice (612).

Abstract: A blow cylinder and a method for actuating the same are provided. The blow cylinder includes a blow piston and a brake piston, wherein the brake piston is controlled independently of the actuation of the blow piston towards the extended position.

Abstract: A valve (200) for a blow molding machine (100) and a method for actuating the same are provided. The includes a housing (202) having an inlet (204) and an outlet (206), a piston (208) movable inside the housing (202), and a pressure compensation chamber (218) positioned between the pressure compensation end (220) of the piston (208) and the housing (202).

Abstract: The invention relates to a fluid flow control assembly for a container blowing machine, comprising: a blow pin (1); a plurality of pipes for the circulation of a blowing fluid, which enable the blowing fluid to flow between at least one blowing fluid source, at least one fluid discharge outlet and the aforementioned blow pin (1); and valves which can control the flow of the blowing fluid inside the plurality of fluid circulation pipes. The invention is characterized in that the valves are all placed on the front of a body (3) housing the blow pin (1).

Abstract: The invention relates to a device for injecting compressed air into a parison, having an injection cylinder, having a hollow shaft arranged inside the housing of the injection cylinder in a manner so as to be displaceable along its longitudinal axis (A), one end of said hollow shaft projecting out of the housing and provided with a connection head for the tight connection to the parison, and having a stretching rod arranged coaxially to the hollow shaft in the interior of the hollow shaft and displaceable coaxially with the hollow shaft. A double piston is arranged axially parallel to the hollow shaft. The double piston is connected to the hollow shaft by a connection lug and thereby moves the hollow shaft along its longitudinal axis (A) between a lower and an upper end position. According to the invention, the active surfaces of the double piston are each arranged in a control chamber connected to a separate control line, which are configured in the housing of the injection cylinder.
