    摘要: The invention relates to a ball valve (1), particularly for use in motor vehicle refrigerant circuits, having an actuator (2), a shaft (3) including a shaft bearing (5), a ball (4) including a ball passage (16), and a valve housing (13). Said ball valve is characterised in that a fluid shaft seal (8) is arranged in the shaft bearing (5) between an upper shaft seal (6) and a lower shaft seal (7), wherein the fluid shaft seal (8) is formed by a cavity (18) in which a sealing fluid is provided, and that the sealing fluid is in contact with the shaft (3) in a sealing region (19) such that the sealing fluid has a sealing effect in the axial direction, wherein the cavity (18) is at least partially formed by a diaphragm (11) and is limited on the shaft (3) by the shaft seals (6, 7), and that the diaphragm (11) is formed in such a way that pressure can be applied to the side facing away from the sealing fluid.

    摘要: The invention concerns an valve drive assembly for a valve unit for regulating a flow of fluid with a lead-through of an operating rod (3) through a flange (4), particularly the arrangement of operating rod (3) to the flange (4) for adjusting a defined flow of fluid. The assembly comprises a flange (4), and operating rod (3) and an annular element. The operating rod (3) is disposed through said flange, and annular element is disposed between flange (4) and operating rod (3) defining an annular gap (12) between the annular element and the operating rod. An effective length of the annular gap (12) exceeds a thickness of the flange (4). This invention leads to considerable cost savings, as the component parts can now be produced more simply using manufacturing processes known from mass production, such as deep-drawing or even stamping.

    摘要: An aseptic valve for regulating supply and discharge of a semi-processed food product in an aseptic storage tank. The valve is provided with a valve body on which is mounted a bonnet housing a bushing. These three elements define three chambers in which a sterilizing liquid is retained. The three chambers bathe parts of the three principal parts of the valve with the sterilizing fluid and maintain paths of entry of microorganisms blocked by the sterilizing liquid so that the valve and the system to which it is connected are maintained sterile.

    摘要: A gas pressurized packing system for use in a control valve may include a first packing member, a second packing member and a pressurized gas supply. The first and second packing members may be arranged about, respectively, lower and upper portions of an operating member that extends through a bore in the control valve. The pressurized gas supply may be configured to pressurize a portion of the bore arranged between the first and second packing members. The gas pressurized packing system may be implemented in a low fugitive emission control valve and a low fugitive emission control valve system.

    摘要: A valve for controlling the temperature of a coolant to flow into a fuel cell stack to provide the optimum level of coolant at the appropriate temperature in order to keep the operation of the fuel cell stack stable is provided. In particular, new type of seal that can achieve maximum sealability with minimized friction force on a plunger shaft by changing the shape and structure of a seal for sealing the plunger shaft. As such, the valve provides a coolant control valve for a fuel cell stack in a fuel cell vehicle which can improve durability in addition to preventing water leakage and can contribute to reducing the manufacturing cost via reduction of the number or parts and simplification of the structure by removing peripheral parts all while sufficiently sealing the valve.
