A rotary vane pump includes a cartridge with a sleeve enclosing a set of rotary vanes on a shaft and end members supporting the shaft. A low pressure inlet to the vanes is formed in one side of each end member and a high pressure outlet from the vanes is formed in the other side of each end member. A pair deformable strips are affixed in grooves in the exterior surface of the cartridge which extend in an axial direction at positions that separate the low pressure inlet side from the high pressure outlet side. The cartridge is inserted into a housing having a fluid inlet port and a fluid outlet port to establish a first path between the fluid inlet port of the housing and the low pressure inlet of the cartridge and a second path between the high pressure outlet of the cartridge and the fluid outlet port of the housing. The deformable strips align the end members and the sleeve. Upon insertion of the cartridge into the housing, the deformable strips are compressed between the cartridge exterior surface and the housing to isolate the first path from the second path.

A system for dispensing fluid may include a first fluid circuit and second fluid circuit. The first fluid circuit may include a first reservoir configured to contain a supply of first fluid for being dispensed and a first variable volume chamber in flow communication with the first fluid circuit. The second fluid circuit may be configured to provide pressure for dispensing the first fluid. The second fluid circuit may include a second reservoir, a pump, fluid passages configured to provide fluid flow within the second fluid circuit, and a second variable volume chamber in flow communication with the second fluid circuit. The second fluid circuit may be a closed-loop circuit, and the first variable volume chamber and the second variable volume chamber are associated with one another, such that flow of fluid in the second circuit controls dispensing and temperature of the first fluid in the first fluid circuit.

A fluid transfer device includes a housing and a reciprocating piston in the housing. The piston and the housing may be configured to at least partially define at least two variable-volume chambers. An inlet chamber port and an outlet chamber port may be associated with each of the at least two chambers. A valve member may be operatively associated with each inlet chamber port and outlet chamber port to permit or prohibit fluid flow past the respective inlet chamber port and outlet chamber port. The two chambers may be in a state of fluid isolation, such that fluid in one of the chambers does not enter into any other chamber. A valve actuating means may be configured to shift the valve members to permit or prohibit fluid flow past the inlet and outlet chamber ports. A release mechanism may be associated with at least one valve member. The release mechanism may be configured to allow the valve actuating means to shift the valve members to permit or prohibit fluid flow past the inlet or outlet chamber ports. A sub-system in a post-mix beverage dispenser is also disclosed using a fluid powered proportioning pump.

A ventilated work chamber, e. g. , a paint booth, large enough to allow a worker to move about inside is improved by confining the zone (or path) of the fresh ventilating air to just a portion of the cross section of the chamber, and providing means for shifting the location of the ventilating air zone from one place to another in the chamber, as the worker changes his location.

A system for supplying at least two fluids in proportioned quantities may include a first and second intake passages configured to be in flow communication with sources of first and second fluids, respectively. The system may include a fluid transfer device in flow communication with the first intake passage and the second intake passage, and a pump in flow communication with the first intake passage. Operation of the pump is configured to supply a quantity of the first fluid to a first chamber of the fluid transfer device such that a quantity of the second fluid is expelled from a second chamber of the fluid transfer device. When operation of the pump is ceased, a quantity of the second fluid enters the second chamber and a quantity of the first fluid is expelled from the first chamber.

A system for spraying fluids at variable flow rate using pulse width modulation utilizing a circuit including a reservoir, pump, spray nozzle, pulse width modulated valve. While no spray issues from a nozzle, the fluid circuit is closed with the reservoir as the initial and end point of the circuit. While no spray issues from a nozzle, the fluid flow through a heated nozzle functions as a heat sink. While spray issues from a nozzle, the circuit contains a means to maintain a specific fluid pressure. While no spray issues from a nozzle, the circuit pressure is much lower than the spray pressure allowing reduced energy consumption and lessening wear on the pump and motor. This system may be incorporated into a selective catalytic reduction (SCR) system for controlling NOX emissions from diesel engines using a urea-water solution as a fluid.

A device utilizing a fluid motor is disclosed. The device comprises a housing and a reciprocating piston in the housing. The piston and the housing may be configured to define at least two variable-volume chambers. A multi-port valve may be associated with the piston, and may be in communication with the at least two chambers. A valve actuating mechanism may be configured to actuate the multi-port valve to affect a fluid path in the device. The device may also include a valve engagement-release mechanism configured to maintain the multi-port valve in a position when the valve is not being actuated. An inlet port and an outlet port may be in selective communication with each piston chamber through the multi-port valve.
