摘要： A flow and pressure stabilization device comprises a housing; a first fluid chamber; a gas chamber; a deformable bladder that separates the first fluid chamber from the gas chamber and at least partially defines a volume of the first fluid chamber; a second fluid chamber in fluid communication with the first fluid chamber via a fluid passage; and a variable flow valve in fluid communication with the second fluid chamber, the variable flow valve comprising: a fluid port in fluid communication with a fluid outlet; a deformable diaphragm positioned adjacent the fluid port, the diaphragm at least partially defining a volume of the second fluid chamber; and an outflow control button coupled to the diaphragm and extending at least partially into the fluid port, the outflow control button comprising an at least partially tapered surface.

摘要： A pulsation dampener includes: a housing having in internal cavity; an expandable bellows positioned within the internal cavity of the housing, the expandable bellows having a proximal end, a distal end, and an expandable portion between the proximal and distal ends; a bellows support member coupled to an interior side of the distal end of the expandable bellows and extending longitudinally away from the distal end of the expandable bellows toward the proximal end of the expandable bellows; and a cap fixed with respect to the housing and positioned to support the bellows support member when the expandable bellows is in a longitudinally compressed configuration.

摘要： A fluid pump inlet stabilizer dampener includes a deformable diaphragm separating an enclosure into a gas chamber and a liquid chamber; and a piston coupled to the deformable diaphragm and being movable with respect to a valve housing, wherein the piston is configured to be positioned in at least first, second, and third positions, wherein in the first position a first fluid flow path from a pressurized gas inlet port to the gas chamber is open, in the second position the first fluid flow path is closed, and in the third position the first fluid flow path is closed and a second fluid flow path that activates a venturi vacuum generator is open.

摘要： A flow and pressure stabilization device includes a housing; a first fluid chamber; a gas chamber; a deformable bladder that separates the first fluid chamber from the gas chamber, the deformable bladder comprising a longitudinally protruding portion shaped such that, when a pressure in the gas chamber is greater than a pressure in the first fluid chamber, the longitudinally protruding portion extends toward the first fluid chamber; and a valve in fluid communication with a fluid outlet, the valve including: a second fluid chamber in fluid communication with the first fluid chamber; a fluid port in fluid communication with the fluid outlet; and a deformable diaphragm positioned adjacent to and biased toward the fluid port.
