Abstract: A pressure controller for a phlegm sucking device includes a seat body, a press element and a control valve. The seat body has a containing space, a gas inlet tube and a gas outlet tube interconnected with each other. The control valve is disposed in the containing space. An upper end and a bottom end of the control valve abut the press element and an upper portion and a bottom of the seat body respectively for blocking or allowing communication between the gas inlet tube and the gas outlet tube. The control valve includes a plastic restoring element. When the plastic restoring element is deformed to have a decreased height, the plastic restoring element allows the control valve to move and provide a resilience. The control valve blocks the communication between the gas inlet tube and the gas outlet tube when the plastic restoring element is not deformed.
Abstract: A damper apparatus possible to suppress abnormal sounds immediately after the locking of gears has been released is provided. In a first lock mechanism of the damper apparatus, a first arcuate outer-peripheral part peripherally adjacent to a teeth-missing gear in a drive gear enters a portion of a plurality of teeth in which some teeth are narrowed in the axial direction to restrain a sector gear, the teeth being meshed with the drive gear in the sector gear. In the tooth nearest to the first arcuate outer-peripheral part in the teeth-missing gear, the curvature of a first tooth flank on the side opposite the first arcuate outer-peripheral part is less than the curvature of a second tooth flank on the first arcuate outer peripheral part side, and the tooth has a curved surface continuous from the first tooth flank to the second tooth flank.

Abstract: A valve positioner that can maintain operation of the control valve despite failures in one or more components. The valve positioner may reduce downtime by allowing in-situ repair to occur on the valve positioner. The valve positioner may incorporate a by-pass component, which can utilize control input signals (e.g., a 4-20 mA signal) to energize one or more components (e.g., a current-to-pressure converter) to cause the control valve to modulate fluid flow without the digital microprocessor and/or related components.
Abstract: A fluidic device controls fluid flow in a channel conduit from a fluid entrance to a fluid exit. In some embodiments, the fluidic device comprises the channel conduit, a flexible element, a cross member, and a gate. The channel conduit is bounded by an inner surface that includes a protrusion. The flexible element is coupled to the inner surface of the channel conduit on a different side of the inner surface as the protrusion. The cross member has a first end that is coupled to a deformable surface that is part of the inner surface of the channel conduit and a second end that is coupled to the flexible element. The gate is configured to deform the deformable surface in accordance with a fluid pressure at the gate. An amount of deformation imparted by the gate controls a position of the flexible element via the cross member.

Abstract: A labor-saving push-button water valve includes a button, a valve core, a valve core spring, and a valve seat. The middle portion of the valve seat is formed with a core chamber. An outer periphery of a front end of the valve core is formed with an annular groove. When the button drives the valve core to move to the position where a water inlet hole is not communicated with a water outlet hole, an annular hydraulic chamber is formed between the valve core and the peripheral wall of the core chamber. The water valve is able to switch the opening and closing of the waterway smoothly by reducing the water pressure applied to the valve core, and reduces the wear of the valve core, and improves the service life and the airtightness of the water saving structure.
Abstract: A regulating valve has a gland portion slidably holding a valve stem and the gland portion includes a lid member having a first through-hole into which the valve stem is inserted, gland packings disposed on a spacer provided between the inner wall of the first through-hole and the valve stem, a packing follower in which a first cylindrical portion is connected concentrically to a second cylindrical portion having an outer diameter smaller than the first cylindrical portion, disc springs laminated with each other on the first cylindrical portion to surround the second cylindrical portion of the packing follower, and a packing flange having a second through-hole into which the second cylindrical portion of the packing follower is inserted, the packing flange being disposed on the disc springs, the packing flange being fixed to the packing follower by fitting the second cylindrical portion to the second through-hole.
