  • Patent number: 6048181
    Abstract: This invention provides a power delivery device (10) for delivering a fixed volume of flowable material to a specific site, the power delivery device (10) comprising pumping means (14) for forcing a predetermined volume of the flowable material through at least one flow path (38,40) of the power delivery device (10) by means of line pressure exerted on the flowable material; and valve means (12), operatively connected to the pumping means (14), for selectively opening and closing the at least one flow path (38, 40) through which the flowable material moves such that the predetermined volume of flowable material can be sprayed out of the power sprayer (10) when the at least one flow path (40) is open and can be redirected to fill the power sprayer (10) when the at least one flow path (40) is closed.
