    摘要: 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). The piston (208) includes a pressure compensation end (220), a valve seat end (222), and a pressure compensation bore (210). The pressure compensation chamber (218) is in fluid communication with the inlet (204) via the valve seat end (222) of the piston (208) via the pressure compensation bore (210). The piston (208) is configured to actuate independently of an inlet fluid pressure (236).

    摘要: 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).

    摘要: A stretch blow molding system (200) is provided. The stretch blow molding system (200) includes a cylinder (201) with a movable stretch rod (202). The stretch blow molding system (200) further includes a proportional pre -blowing valve (204) including a first fluid port (204a) in fluid communication with a first pressurized fluid source (244) at a first pressure and a second fluid port (204b) in fluid communication with the cylinder (201) and selectively in fluid communication with the first fluid port (204a). The stretch blow molding system (200) further comprises a blowing valve (214) including a first fluid port (214a) in fluid communication with a second pressurized fluid source (247) at a second pressure, higher than the first pressure, and a second fluid port (214b) in fluid communication with the cylinder (201) and selectively in fluid communication with the first fluid port (214a).
