An air vent valve assembly for a tank assembly of a beverage maker for aircraft includes a valve housing having an interior chamber and an inlet flow passage in fluid communication with the interior chamber, and a valve base that mates with the valve housing. The valve base is configured and adapted to be attached to a tank assembly of a beverage maker. The valve base includes an interior flow chamber in fluid communication with the interior chamber of the valve housing and a flow outlet in fluid communication with the interior flow chamber of the valve base. The air vent valve assembly includes an umbrella valve operatively connected to at least one of the valve housing or the valve base between the flow outlet of the valve base and the inlet flow passage of the valve housing.

A ball float vent valve includes a valve body having an inlet port, an outlet port and an axial passageway there-between. The passageway may be defined by a cylindrical inlet chamber, a cylindrical outlet chamber and a tapered seat connecting the inlet chamber and outlet chamber. The outlet chamber may include an annular retaining groove proximate the outlet port. A spherical float may be positioned in the outlet chamber. The float may be dimensioned to seal the passageway when seated on the tapered seat. A retainer positioned in the retaining groove may include an outer crescent region having a plurality of apertures, a center region dimensioned to retain the float in the outlet chamber, and a linking region connecting the outer region to the center region.

A tip valve and a cook system incorporating same that automatically stops the flow of gas to a burner when tipped over and that automatically resets when disconnected from the fuel canister to allow the flow of gas to resume when righted and reconnected are provided. The tip valve includes a ball bearing freely moveable between a fuel canister actuator pin and a tip seal within a bore having two different diameters at each end thereof. The transition between the two diameters forms a taper that may be continuous forming a smooth tapered bore, or discontinuous formed by at least one counter bore. The automatic resetting is provided without the use of a mechanical pin or member.

Provided are a check valve which can be easily mounted, a check valve structure which includes the check valve, and a hydraulic system which has the check valve structure. A check valve structure includes a partition wall for defining a first hole including a part of a hydraulic passage, and also includes a check valve inserted in the first hole, wherein the check valve structure is provided with: a base body having a base section which closes an open end of the first hole, and having a tubular section which has one end connected to the base section; and a sphere capable of making contact with the other end of the tubular section. The tubular section has formed therein a first through-hole communicating with a second hole connected to the first hole.

A gas safety valve for controlling a gas flow includes a valve body providing a body inlet port for coupling to a first gas supply and a body outlet port for coupling to an appliance, the valve body extending along a longitudinal axis between the body inlet port and the body outlet port, the valve body further providing an inlet bore extending downstream from the body inlet port, and an outlet bore extending to the body outlet port. A valve has a valve chamber having a valve inlet and a valve outlet, a ball located within the valve chamber and a valve seat provided at the valve outlet such that the ball is retained in the valve chamber upstream of the valve seat. The valve body includes an internal junction positioned upstream of the valve inlet, and a side inlet port.

A drop-in insert for a valve cage is adapted for use with a subsurface pump. The insert can be positioned in a valve cage housing. The insert includes a cradle, a base, a plurality of angled ribs, and an upper ring. In one embodiment, the insert may also include an extended nose region. Upper ring can abut an interior diameter of the housing, providing a smooth transition for pumped fluid, thereby decreasing turbulent fluid flow and promoting improved fluid flow during pumping operations. The insert can be dropped into position in the housing. Alternatively, the insert can be positioned in the housing by an interference fit or the like. The housing and insert can be part of a valve cage assembly that includes a ball, seat, seat plug, and end cap. The assembly may include an O-ring component which can cushion the insert, thereby prolonging the life of the insert.

A valve assembly includes a valve body defining a fluid inlet in fluid communication with a fluid outlet. The valve body has an inner body surface defining an interior chamber extending between the fluid inlet and the fluid outlet. A valve element is disposed within the interior chamber and rotatable through a range of positions relative to the outlet providing a high level of precision control of a fluid flow rate through the valve assembly. A valve seat with a seal is positioned around a valve element. The valve seat is configured to self-adjust its inner radial diameter to correspond to the outer radial diameter of the valve element to maintain a portion of an inner seat surface in contact with an outer valve surface of the valve element through the range of positions.

A valve body, including a first cavity, a second cavity communicated with the first cavity through a second water inlet of the second cavity, a valve core and an elastic reset member; the valve core, arranged in the first cavity and coaxial with the second water inlet, includes a piston and a first ejector rod being coaxial with the piston; the piston is configured to open or close the second water inlet; the elastic reset member is configured to press the valve core to move in the axial direction to close the second water inlet. A self-locking level control valve is adopted. The water purifier achieves no reactive power loss, low emission and safe water quality, avoids frequent startup of the water purification system, and solves the technical problem of the “first glass of water” brought by the ultra-low pressure reverse osmosis pumpless water purification system.

A valve device includes: a casing including a valve chamber; a valve seat disposed in the valve chamber and including a valve hole; a float disposed in the valve chamber and movable in accordance with the amount of drain in the valve chamber to thereby open and close the valve hole; and a support supporting the float in the state of being seated on the valve seat and closing the valve hole. The support includes a base including an opening and having a frame shape, and two float seats disposed in the base, and the float in the state of being seated on the valve seat and closing the valve hole is seated on the two float seats.

A fluid control device includes: a joint block defining a fluid flow path open to an upper surface thereof, and which has an engaging portion on the bottom surface side thereof; a support member having a guide portion which restrains the joint block on the upper surface while permitting the joint block to move in longitudinal direction; and a fluid device fixed to the upper surface of the joint block. The support member is provided with at least one plunger such that the tip end portion protrudes from the upper surface of the support member. A recess is provided in the bottom surface of the joint block, and the recess engages with the tip end portion of the plunger to set the position of the joint block in the longitudinal direction.
