A cam liner for use in an integrated drive generator has a cam liner body extending between a first end spaced from the second end by a first distance. The body is generally cylindrical. An outer diameter of the cam liner defines a second distance. A ratio of the first distance to the second distance is between 0.90 and 1.00. An integrated drive generator and a method are also disclosed.

A diaphragm pump includes a pump body mechanism, a one-way valve mechanism, a diaphragm mechanism, and an eccentric mechanism, wherein the one-way valve mechanism, the diaphragm mechanism and the eccentric mechanism are mounted at the pump body mechanism. The one-way valve mechanism includes a valve cover and a one-way valve mounted at the pump body mechanism via the valve cover. The diaphragm mechanism includes a pump cover and a diaphragm connected to the pump cover. The pump cover is mounted at the pump body mechanism and covers the diaphragm and the valve cover. The diaphragm is detachably connected to the eccentric mechanism. The pump cover and the diaphragm jointly form a diaphragm cavity, and an inner side of the pump cover is provided with a flow channel communicating with the diaphragm cavity and configured to allow liquid to flow into or out of the diaphragm cavity through the flow channel.

A compressor control module (CCM) controls an output of a variable displacement swash plate compressor. The CCM directly calculates, or receives from an external source, a signal indicating a desired or required output from the compressor, receives a current value of the desired or required output, and receives or calculates a current rotation speed and angle, with respect to a rotation axis, of a swash plate, or a current piston stroke length and a reciprocating frequency of the compressor. The CCM determines a difference between the desired or required output from the compressor and the current value and outputs a signal to a valve driving unit which will adjust an angle of a swash plate such that the actual value becomes closer to, or the same as, the desired or required output, taking into account the additional values received or calculated in the receives or calculates step.

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.

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 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.
