Abstract:
A power delivery device for delivering a fixed volume of flowable material to a specific site, the power delivery device comprising:a pump assembly including a main body defining a pumping chamber and a piston slidably received within said pumping chamber, said pumping chamber being divided by said piston into a first compartment for metering the fixed volume of flowable material and a second compartment;an inlet for delivering pressurized flowable material to said first compartment and said second compartment of said pumping chamber;a valve assembly operatively communicating with said pump assembly; andan outlet for releasing the fixed volume of flowable material to the specific site, said valve assembly selectively opening and closing said outlet such that the pressurized flowable material passes from said inlet to fill said first compartment of said pumping chamber when said outlet is closed and the fixed volume of flowable material in said first compartment can be released through said outlet when said outlet is open, and said piston forcing the fixed volume of flowable material through said valve assembly by means of pressure exerted on said piston by said pressurized flowable material.
