摘要： A device for dispensing a fluid product, includes: a container containing the product; an electric motor including a rotatably driven shaft; a dispensing system actuated by motor rotation, the quantity of product dispensed depending on the motor rotation; a switching body to control the motor; a stop control element rotatably driven by the shaft, assuming an active position during the rotation thereof in which it causes the switch to interrupt the power supply of the motor; and a restarting circuit to switch into an activated state, when triggered, to force the starting of the motor when the stop control element is in an active position, the restarting circuit remaining activated long enough for the stop control element to leave its active position, the restarting circuit becoming inactive such that the motor stops operating when the stop control element regains its active position once the restarting circuit is inactive again.

摘要： A reciprocating pump and transmission assembly having a one-way clutch is disclosed. The transmission includes an input shaft with an eccentric element, a drive link rotatably connected at one end to the eccentric element and at the other to a driven arm. The driven arm is connected to a driven shaft via a one-way clutch. The oscillating motion of the eccentric drives the drive link and driven arm and the one-way clutch translates that motion into incremental motion of the driven shaft. By changing the stroke length of the drive link various gear ratios between the drive shaft and driven shaft are achieved. The driven shaft then uses a mechanism such as a Scotch Yoke to create reciprocating motion to drive one or more pumping elements.

摘要： The present disclosure relates to a method of monitoring an electric motor serving to drive a pump, wherein, within a time interval T, current values are measured, an average value of the current values measured is determined and this average value is compared to a predetermined reference value. According to the disclosure, it is provided that the method extends to controlling the electric motor, wherein the current values measured reflect the profile of the winding current of the electric motor and, irrespective of whether they can be associated with an instantaneous maximum value of the current profile, are included in determining the average value, and wherein the average value is considered by the motor control as input parameter.

摘要： An electromagnetic vibrating diaphragm pump capable of increasing pump efficiency by increasing the vibration amplitude of the vibration of diaphragms even when the pressure inside a compression chamber is high. Diaphragms are fixed to both end portions of an oscillator having magnets. AC driven electromagnets are provided in a manner to face the magnets of the oscillator. A frame adhered to the outer peripheries of the diaphragms covers the electromagnet side, and pump casings cover the opposite sides. The pump casing includes a compression chamber adjacent to the diaphragm, a suction chamber connected to the compression chamber via a suction valve and an exhaust chamber connected to the compression chamber via an exhaust valve, the suction chamber or the exhaust chamber being connected to the frame via a continuous hole.

摘要： Apparatus and associated methods relate to nutating a piston drive linkage oriented around a longitudinal axis in response to the rotation of a drive shaft about a drive axis of rotation, said longitudinal axis being offset and canted with respect to said drive axis of rotation. In an illustrative example, the piston drive linkage may be formed as an umbrella shape with multiple arm members extending radially from the longitudinal axis. The distal ends of each of the radial arm members may attach to a stationary piston crank. The nutating motion of the piston drive linkage may impart a substantially linear motion profile substantially parallel to the drive axis of rotation. A shaft extending along the longitudinal axis from the piston linkage may advantageously freely insert into and rotate within a receptacle of a spinner body being rotated around the drive axis of rotation.
