摘要： Embodiments of the present invention may include a turbocharger having a turbine, a turbine housing, a variable valve, a first plate, a second plate and a heat shield member. The turbine housing accommodates the turbine and has a flow path. The variable valve rotates about each pivot member provided thereon, thereby adjusting the flow velocity of fluid guided from the flow path to the turbine. The first plate supports one end of each pivot member, and defines the flow path. The second plate supports the other end of each pivot member or the variable valves, and defines the flow path. The heat shield member covers a wall surface of the turbine housing, and defines the flow path.

The proposed valve device includes an inlet port and an outlet port connected by a fluid flow channel. The valve device further includes a first valve and a second valve housed in a common casing. The first valve includes a first valve head mounted on an annular-shaped first spindle. The second valve includes a second valve head mounted on a second spindle, the second spindle extending concentrically and slidably through the annular-shaped first spindle. The first and second valves are displaceable along a common axis and operable to influence fluid flow between the inlet port and the outlet port through the flow channel.

摘要： A plug for regulating a flow of gas in a system is disclosed. The plug includes a housing disposed on a temperature boundary in a system. The housing defines a passage for flowing gas therethrough. The plug further includes at least one pressure-actuated valve disposed in the passage and movable between an open position and a closed position. The at least one pressure-actuated valve moves from the open position to the closed position as the pressure of the gas increases and moves from the closed position to the open position as the pressure of the gas decreases.

摘要： It is intended to provide a steam valve, which can reduce vibrations of each part of the steam valve, can suppress pressure loss and can cut off the steam rapidly. The steam valve 1 changes an area of a flow path between the valve seat 4 and the valve body 2 and adjusts a flow of steam passing through the flow path by moving the valve body 2 relative to the valve seat 4. The valve body 2 satisfies a relationship of r>0.6D0, where r is a curvature radius of the valve head portion 2A and D0 is a seat diameter of the valve seat 4. A tapered portion 2B is provided on an upstream side of the valve head portion 2A and its surface is tilted toward a direction of relative movement of the valve body 2 to the valve seat 4 more than that of the valve head portion 2A.

摘要： The invention relates to an electromechanical drive for actuating valves, especially in steam turbines including an electromotor, a linear unit, a clutch and an electronic control unit. The linear unit includes a piston rod which is guided in a power-transmission thread of a screw nut, and is arranged, at least in sections, as a spindle and is displaceable along its longitudinal axis for actuating the valve in the screw nut with the power-transmission thread. The clutch is arranged for transmitting a rotational movement of the motor axis of the electromotor onto the piston rod. The electronic control unit is set up to control the speed and/or rotor position of the motor axis of the electromotor depending on a control signal and an output signal of a position pick-up of the position of the piston rod in the screw nut with power-transmission thread, and/or to control the engagement and/or disengagement of the clutch depending on the control signal.
