Definitions

  • the present invention relates to an improved pneumatic pedal assembly.
  • pedal driving assemblies are frequently used for small size or micro motors,for example for the dentistry field and goldsmith's art, as well as in washing machines.
  • valves used for controlling servovalves are however of comparatively great size (from 1/8" to 1/4") or they are paired or pair coupled,that is one pneumatic valve associated with an electric valve.
  • a pedal usually controls a remote control switch in turn controlling the driving coil of a servocontrol operating either a cylinder or another cylinder of a two cylinder operating assembly.
  • the document DE-A-31 29 355 discloses a pneumatic pedal assembly having substantially the features of the pre-characterizing portion of the main claim.
  • the present invention sets out to overcome the above mentioned drawbacks, by providing a pedal control assembly bypassing the electric aspect or elements of a control of the above mentioned type and which operates on servocontrol coils or solenoids by pneumatically operating on said servo-control.
  • a main object of the present invention is to provide such a pedal assembly which comprises exclusively pneumatic component thereby reducing to a minimum the making cost and maintenance and repairing requirements.
  • Another object of the invention is to provide such a control pedal assembly specifically designed for washing machines.
  • control pedal assembly comprises a reduced size casing, indicated at the reference number 1, a pedal element 2 and either a 3-way or a 5-way valve body.
  • the control pedal assembly according to the present invention is specifically provided for actuating a pneumatic servo-control in which the operating fluid,for example filtered and lubricated air,efficiently operates through the overall required temperature and pressure range,depending on the preset passage diameter and cross-section.
  • the operating fluid for example filtered and lubricated air
  • the casing 1 is preferably made of a black galvanized sheet metal,passivated against corrosion, arid in the bottom of said casing there are formed threaded holes 6 for receiving screws for connecting the control pedal assembly to the machine to be controlled.
  • the valve body 7 is made of anodized aluminium,whereas the spool member 8 is made of processed brass,the gaskets 9 being of conventional type.
  • control pedal assembly can be provided with a protective cover 10 (fig.4).
