摘要： In some embodiments, a valve may include a core defining a first channel, a second channel, and a third channel. The core may be configured to rotate to at least a first position, a second position, and a third position. When the core is in the first position fluid flow may be facilitated in a first direction through the first channel and the third channel. When the core is in the second position fluid flow may be facilitated in a second direction through the third channel and the first channel. When the core is in the third position fluid flow may be facilitated in a third direction through the second channel. The valve may also include a housing having a first input port, a first output port, a second input port, and a second output port positioned on the housing. The core may be disposed within the housing.

摘要： A cartridge valve includes a housing, a stem adapter, and a stem assembly. The stem adapter includes a body defining a first hole, which extends in a longitudinal direction. The stem assembly includes a first stem component and a second stem component. The first stem component includes an arm and a spherical portion that is configured to be at least partially positioned within the first hole and defines an opening. The second stem component has a body that is configured to be at least partially received within the opening of the first stem component. The spherical portion is configured to expand in size in response to the first end inserting a portion of the body of the second stem component into the opening in the first stem component, which increases a frictional resistance induced by relative rotation between the stem assembly and the stem adapter.

摘要： A valve core with a flow-through rod, has a valve seat, a valve shell, a certain valve plate, a movable valve plate, a valve plate, a connecting piece, a flow penetrating rod, a blocking piece and a detent structure, wherein the detent structure is used for stopping reciprocating actuation of the blocking piece, so that the water pressure forms a difference change; and the valve piece is elastically driven to change whether water flows out outwards, and the connecting piece is connected with the movable valve piece, so that the movable valve piece can be locked to rotate, and the water flowing out of the outside can be adjusted and controlled.

摘要： A control system provides automated control of gas washout of a patient interface, such as a mask or nasal prongs. A gas washout vent assembly of the system may include a variable exhaust area, such as one defined by gears, radial exhaust revolvers and/or flow diverters for a conduit having a variable gas passage channel. The vent assembly may be attached substantially near or included with the patient interface. An actuator of the assembly, such as a solenoid, motor or voice coil, manipulates the vent assembly. The actuator may be configured for control by a processor to change the exhaust area of the vent assembly based on various methodologies including, for example, sleep detection, disordered breathing event detection and/or leak detection.

摘要： The disclosure discloses a servo-valve that controls a fluid discharged from a discharge port of a nozzle by displacing the nozzle and drives an actuator. The servo-valve includes a receiver that includes an inflow surface provided with a first inflow port and a second inflow port into which the fluid discharged from the discharge port flows. The nozzle includes a force generation portion that includes an end surface provided with the discharge port and an outer circumferential surface formed in the periphery of the end surface. When the nozzle is displaced from a neutral position toward the first inflow port, the fluid inside the second inflow port is blown out toward the nozzle. The force generation portion collides with the fluid blown out from the second inflow port and causes an assisting force in a direction matching a nozzle displacement direction toward the first inflow port. The nozzle easily moves by the assisting force generated in the force generation portion and thus a response speed is improved.

摘要： A regulator assembly having a main body is provided. The main body includes a first passage extending from a first end and a second passage extending from the first passage towards a second end. The main body also includes a seat defined between the first passage and the second passage. The regulator assembly also includes a valve element. The valve element includes a head portion having a projection. The projection includes a plurality of apertures provided therethrough. The valve element further includes an internal channel. The regulator assembly further includes a spring element. Direct fluid communication between the plurality of apertures of the valve element and the first passage of the main body is discontinued when the head portion is in contact with the seat; and is in direct fluid communication with the first passage of the main body when the valve element is not in contact with the seat.
