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： A valve (10) comprising a bore (14) extending about an actuation axis (A), wherein a spool (34) inside the bore (14) is actuated between a first working position and a second working position, and a first circumferential seal wing (56A) and a second circumferential seal wing (56B) being arranged on the spool (34). In the first working position, the first seal wing (56A) abuts to an outer first recess wall (24a) and the second seal wing (56B) abuts to an inner second recess wall (24c), so as to open some flow paths and close other flow paths. In the second working position, the first seal wing (56A) abuts to an inner first recess wall (24b) and the second seal wing (56B) abuts to an outer second recess wall (24d), so as to close some flow paths and open other flow paths.

摘要： A device used for pneumatic control, includes a control piston carried in a cylinder. The control piston is mounted so as to be movable in the direction of a longitudinal piston axis, and a primary flow path that can be closed by the control pressure passes through the cylinder. The control piston is provided with a control surface that faces a control chamber of the cylinder and that is designed to transmit a control force to the control piston. The control piston is made at least partially of a plastic.
