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 the other.
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 characterized in that said control pedal assembly comprises a small size casing, a reduced stroke pedal element and a valve body,of the 3-or 5 way type, so assembled as to provide a very compact device.
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, and 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.
