Abstract: Retractable handle assembly used in a valve of an Intermediate bulk container (IBC) includes a valve body, a valve core, and a valve stem. The valve stem is used to drive the valve core to move so as to open/close the valve. The handle of the handle assembly is connected to the valve stem and can be rotated around the central rotating axis of the valve stem. When the valve needs to be opened/closed, the handle is rotated around the central rotating axis to a deployed state to open/close the valve. The handle is rotated around the central rotating axis to a retracted state so as to reduce the space occupied by the valve for the valve to be welded to the liner bag or installed to IBC. The handle can be switched between a deployed state and a retracted state.

Abstract: To achieve a compactly designed, simple and robust control valve for a hydrodynamic torque generator which is linear over a wide adjustment range, the control channel (12) of the control valve is formed in such a way that a substantially linear relationship between valve position (?) and flow ({dot over (V)}) is achieved by rotating the valve body (6) between a first valve position (?1), which differs from the closed position, and a second valve position (?2) with a larger flow ({dot over (V)}) than in the first position (?1).

Abstract: Aspects of the disclosure relate to an overload protection valve for automatic release of a load. The valve may include an outer housing having an end wall, a cam, and inner slide, and an overload spring. The inner slide may include a side wall, a shelf area, an internal barrier, an inlet and an outlet. Each of the inlet and outlet may include an opening through the side wall, and the inlet and the outlet may be separated by the internal barrier. The overload spring may be arranged between the end wall and the shelf area, and may define a load on the valve which will cause the valve to open. The cam may be configured such that when the valve is closed, the defined load will cause the cam to rotate thereby allowing the openings of the inlet and outlet to be in fluid communication and open the valve.

With regard to the at least one double-seal seat, the ratio between first and second areas enclosed by first and second sealing lines in projection along the sleeve longitudinal axis, respectively, is between 6/10 and 10/6.

Abstract: In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow, which causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes exposing an air medium in the fuel tank to ionizing radiation to increase a level of ionization of an air medium in the fuel tank and increase a rate of dissipation of the electrostatic charge. The method includes determining the level of ionization of the air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.
