A suction damping device for a variable displacement compressor includes a rotor rotatably received within a stator disposed in a suction port of the variable displacement compressor. The rotor includes an aperture and the stator includes a pair of opposing openings in selective fluid communication with the aperture of the rotor. An electromagnetic device controls a rotational position of the rotor relative to the stator based on a condition of an electrically controlled valve used to control an angle of inclination of a swashplate of the variable displacement compressor. A changing of the rotational position of the rotor relative to the stator causes a variable overlap to be formed between the aperture of the rotor and the openings of the stator to control a flow of a refrigerant through the suction damping device.

An electro-hydraulic piston pump system comprising an electric motor (16), first and second hydraulic piston pumps (30,60), a first hydraulic actuator (90) having a first port (93) connected directly to a first port (48) of the first pump and a second port (94) connected directly to a second port (49) of the first pump, a second hydraulic actuator (100) having a third port (103) connected directly to a third port (78) of the second pump and a fourth port (104) connected directly to a fourth port (79) of the second piston pump, wherein an external force applied to the first hydraulic actuator (90) that provides a negative pressure differential to the first pump applies an assistive torque to a common motor shaft (18) driving both the first pump (30) and the second pump (60), and an external force applied to the first and second actuators (90,100) that provides a summed negative pressure differential to the first and second pumps (30,60) recharges a power supply for the motor (16).

A pump or combination pump/mixer device is disclosed. The pump or pump/mixer uses moving diaphragms in combination with check valves to pump and/or mix fluid. A main inlet is located at the top of the pump and is fed by a vessel or container that contains fluid. The fluid, in response to the moving diaphragms, passes through an outer chamber into a plurality of lower chambers and then into a central chamber where the fluid then exits via one or more outlets. A series of check-valves are used to ensure one-way flow of fluid through the chambers. The drive shaft of a motor or drive unit drives a nutating disk or wobble plate that actuates the diaphragms to drive fluid through the device. In the pump/mixer configuration, one or more additional inlets are provided to input additional fluids into the device for mixing within the inside of the pump/mixer.

An apparatus for the automated filling of cartridges of e-vapor devices may include a filling drum configured to receive at least one cartridge of an e-vapor device. The apparatus may additionally include a needle assembly including at least one hypodermic needle. The needle assembly is configured to transition between a lowered state and a raised state. The lowered state is where the hypodermic needle is moved down into the cartridge, while the raised state is where the hypodermic needle is lifted up and away from the cartridge. The apparatus may further include a pump assembly configured to pump a pre-vapor formulation into the cartridge when the needle assembly is in the lowered state. The pump assembly may include a variable amplitude cam system configured to adjust an amount of the pre-vapor formulation for pumping to the cartridge without changing start and stop times for the pumping.

A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between an extended position and a retracted position. A pump engagement body engages with the movable pump member for effecting movement of the movable pump member. A first cam surface and a second cam surface are connected to the pump engagement body, at least one of the first cam surface and the second cam surface comprising an adjustable cam surface whose location relative to the pump engagement body is selectively adjustable. A camming body engages with the first cam surface and the second cam surface to effect movement of the pump engagement body, and a dose adjustment mechanism allows the location of the adjustable cam surface relative to the pump engagement body to be selected.

In a variable displacement compressor 100, transmitting member 116 transmits rotational motion of rotor 112 to swash plate 111 and supports swash plate 111. Guide member 117 guides inclining motion of swash plate 111 such that a top dead center position of piston 126 is maintained to be substantially constant. Members 116, 117 are separately formed at different portions on a rotor end face 112a. In the variable displacement compressor 100, first contacted member 118 contacted with transmitting member 116, and second contacted member 119 contacted with guide member 117, are separately formed at different portions on swash plate end face 111b. The transmitting member 116 and the first contacted member 118 extend on rotor 112 and swash plate 111, respectively, from a top dead center side region V1 to a bottom dead center side region V2 of the piston.

A capacity control valve (1) for controlling a flow rate or pressure of a variable capacity compressor according to a valve opening degree of a valve section includes: a valve main body (10) having a first valve chamber (14), a second valve chamber (15) and a third valve chamber (16); a valve body (20) having an intermediate communication passage (26) for allowing communication between the first valve chamber and the third valve chamber, a first valve part (21a) arranged in the first valve chamber, a second valve part (21b) for opening and closing communication between the third valve chamber and the second valve chamber, and a third communication hole for allowing communication between the third valve chamber and the intermediate communication passage; a solenoid (30) having a first plunger connected to the valve body; and a second plunger (37) arranged between the solenoid and the valve body.

A control arrangement controls a position of a swashplate in an axial piston pump between a no-stroke position and a maximum stroke position. The control arrangement includes a servo spool mounted for limited sliding movement in a compensator piston cylinder. A solenoid coil is configured to provide a coil force to move the servo spool. A compensator piston is mounted in the compensator piston cylinder in response to movement of the servo spool. A spring between the servo spool and the compensator piston provides a spring force in response to the coil force applied to the servo spool. The control arrangement defines a feedback system configured to maintain a balancing relationship between the spring and coil forces to enable infinite control of the swashplate position.
