摘要： A sequentially activated multi-diaphragm foam pump for a foam dispenser includes a housing with a liquid pump portion and air pump portion secured to the housing. The liquid pump portion has a liquid inlet, a liquid inlet valve, a liquid pump diaphragm, a liquid outlet valve, and a liquid outlet. The air pump portion has a first and second air inlet, a first and second air inlet valve, a first and second air pump diaphragm, and a first and second air outlet. The sequentially activated multi-diaphragm foam pump also includes a mixing chamber that is in fluid communication with the liquid outlet, the first air outlet, and the second air outlet. The liquid pump diaphragm, the first air pump diaphragm, and the second air pump diaphragm operate in sequential order. The liquid pump diaphragm pumps liquid into the mixing chamber, the first air pump diaphragm pumps air into the mixing chamber to mix with the liquid to form a liquid air mixture, and the second air pump diaphragm pumps air into the mixing chamber to mix with the liquid air mixture to form a foamy mixture. The foamy mixture is dispensed through an outlet that is in fluid communication with the mixing chamber.

摘要： A pumping mechanism is disclosed that includes a plurality of peristaltic pumping actuators configured to selectively and sequentially compress adjacent portions of a first portion of an at least partially compressible pumping element having an inlet that is upstream of an outlet. The plurality of pumping actuators are further configured to reciprocate at a common drive frequency with a first phase offset between each adjacent pair of pumping actuators. The pumping mechanism also includes at least one compensation actuator arranged to selectively compress a second portion of the at least partially compressible pumping element that is disposed between the first portion and the outlet. The at least one compensation actuator is configured to reciprocate at an optimal displacement and at a modulation frequency that is an integer multiple of the fundamental drive frequency and with a second phase offset between the at least one compensation actuator and the adjacent pumping actuator.

摘要： A diaphragm pump includes a motor, an eccentric member driven by the motor, and a diaphragm. The motor includes an output shaft connected with the eccentric member. The eccentric member includes multiple arms which move up and down due to the rotation of the output shaft. The diaphragm has multiple bladders. Each bladder forms a pump chamber. The bladders are connected with the arms such that the bladders are compressed or expanded due to the movement of the arms. The pump has an air exhaust chamber and an air inlet chamber. The air inlet chamber is connected to the pump chambers via a passage. The passage includes a cavity which overlaps the air exhaust chamber in an axial direction of the motor.

摘要： A pump chamber for compressing a liquid such as engine fuel is formed inside a bellows, and the liquid is aspirated into the pump chamber from a suction check valve when the bellows elongates. After the liquid in the pump chamber is pressurized by the contraction of the bellows, it is discharged from a discharge check valve. By providing a fill member for eliminating a dead space in the pump chamber, the formation of air bubbles in the pump chamber is suppressed.
