摘要： A thin gas transportation device includes an inlet plate, a resonance sheet, an actuating element, a first insulation frame attached to the actuating element, a conductive frame, and a second insulation frame attached to the conductive frame. The conductive frame has a conductive outer frame attached to the first insulation frame, an elastic conductive pin, and a conductive piece connected to an outer edge portion of the conductive outer frame. One end of the elastic conductive pin is connected to an inner edge portion of the conductive outer frame, and the other end of the elastic conductive pin extends obliquely toward the actuating element and forms a bent portion. The bent portion presses against the actuating element and is electrically connected to the actuating element, and the bent portion is strip-shaped.

摘要： A pressure reducing valve includes a piston disposed in a cylinder chamber; a valve element that is coupled to the piston and opens and closes a valve seat; a valve spring that biases the valve element in a direction in which the valve element is moved away from the valve seat; and a biasing member that biases the valve seat toward a side opposite to the piston. The pressure reducing valve is configured to reduce a primary pressure of a fluid to a secondary pressure. The valve seat is disposed such that the valve seat reciprocates in the same direction as a direction in which the valve element reciprocates in the primary pressure chamber. As a difference between the primary pressure and the secondary pressure increases, the valve seat moves toward the secondary pressure chamber.

摘要： A fuel pump includes a fuel pump housing made of stainless steel and having a pumping chamber therewithin, a plunger bore extending thereinto, an inlet passage extending thereinto, and an outlet passage extending thereinto. A pumping plunger reciprocates within the plunger bore such that an intake stroke of the pumping plunger increases volume of the pumping chamber and a compression stroke of the pumping plunger decreases volume of the pumping chamber. An outlet valve controls fuel flow from the pumping chamber out of the fuel pump housing. The outlet valve includes an outlet valve seating surface formed by the fuel pump housing within the outlet passage such that a nitrided layer extends from the outlet valve seating surface into the fuel pump housing. The outlet valve also includes an outlet valve member within the outlet passage which is moveable between a seated position and an unseated position.

摘要： A control assembly can be configured for use with a pressure regulator having a valve body defining a fluid flow path. The control assembly can include a control member, a stem, and a lever, and can be disposed within the pressure regulator to selectively control fluid flow. The control assembly can include a primary control member and a secondary control member, or a mechanical stop that can operate to restrict flow along the fluid flow path, including when the stem disconnects from the lever.

摘要： In some examples, a pressure regulating valve comprising a pressure chamber, a compressor configured to establish fluid communication with the pressure chamber, a vent valve configured to establish fluid communication with the pressure chamber, a pressure sensor, and a controller. The controller may determine a pressure based on the signal generated by the pressure sensor, and compare a pressure setpoint and the pressure. The controller may be configured to alter the pressure in the pressure chamber based on the comparison between the pressure setpoint and the pressure. For example, the controller may control the compressor to increase the pressure in the pressure chamber and/or control the vent vale to decrease the pressure in the pressure chamber. The altered pressure of the pressure chamber may generate movement of a restricting element within the pressure regulating valve.
