Claim 2

A system for automatically washing and drying fluid conduits, said system comprising, a fluid tank having an openable drain, drain closing means, supply means for supplying water to said tank, fluid circulating means in fluid receiving communication with a conduit to be washed and dried, a dryer for heating and blowing air; a two way intake valve connected to said conduit and when in one position being in fluid receiving communication with said tank whereby fluid from said tank is conducted through said conduit to wash the latter, said intake valve when in another position being in air receiving communication with said dryer whereby air is forced through said conduit to dry the latter; a two way discharge valve having a fluid receiving connection with said fluid circulating means and also having a discharge to said tank, whereby when said discharge valve is in one position fluid from circulating means is discharged into said tank, and when said discharge valve is in another position fluid from said circulating means is dumped; each of said two way valves comprising, a housing having an upper nipple, an intermediate nipple, and a lower nipple, baffle plate means in said housing and defining an upper chamber and a lower chamber therein, a shiftable control rod extending into said housing and having an inner end in said housing and an outer end outside of said housing, a stopper fixed on the inner end of said rod and engageable with said seat for sealing said lower chamber from said upper chamber, said upper nipple and said intermediate nipple being in fluid communication with said upper chamber and said lower nipple being in fluid communication with said lower chamber, and means for shifting said stopper between an open position in which said lower chamber communicates with said upper chamber and a closed position on said seat in which said lower chamber is not in communication with said upper chamber; and electrical control means including a timer, said control means operative to (1) actuate said water supply means to fill said tank, (2) actuate said fluid circulating means, (3) actuate said drain closing means, (4) shift the positions of said two way valves, and (5) actuate said dryer, all in timed sequence.

Claim 3

A system for automatically washing and drying fluid conduits, said system comprising, a fluid tank having an openable drain, drain closing means, supply means for supplying water to said tank, fluid circulating means in fluid receiving communication with a conduit to be washed and dried, a dryer for heating and blowing air; a two way intake valve comprising; a housing having an upper nipple, an intermediate nipple, and a lower nipple, baffle plate means in said housing and defining an upper chamber and a lower chamber therein, a shiftable control rod extending into said housing and having an inner end in said housing and an outer end outside of said housing, a stopper fixed on the inner end of said rod and engageable with said seat for sealing said lower chamber from said upper chamber, said upper nipple and said intermediate nipple being in fluid communication with said upper chamber and said lower nipple being in fluid communication with said lower chamber, said stopper being shiftable between an open position in which said lower chamber communicates with said upper chamber and a closed position on said seat in which said lower chamber is not in communication with said upper chamber; said intermediate nipple having a fluid connection with said conduit to be washed and dried, said upper nipple having a fluid receiving communication with said tank whereby fluid from said tank is conducted through said conduit to wash the latter, said lower nipple having an air receiving communication with said dryer whereby air is forced through said conduit to dry the latter, a two way discharge valve having a fluid receiving connection with said fluid circulating means and when said discharge valve is in one position fluid from circulating means is discharged into said tank, and when said discharge valve is in another position fluid from said circulating means is dumped; and electrical control means including a timer, said control means operative to (1) actuate said water supply means to fill said tank, (2) actuate said fluid circulating means, (3) actuate said drain closing means, (4) shift the positions of said two way valves, and (5) actuate said dryer, all in timed sequence.

Claim 4

A system for automatically washing and drying fluid conduits, said system comprising, a fluid tank having an openable drain, drain closing means, supply means for supplying water to said tank, fluid circulating means in fluid receiving communication with a conduit to be washed and dried, a dryer for heating and blowing air; a two way intake valve comprising; a housing having an upper nipple, an intermediate nipple, and a lower nipple, baffle plate means in said housing and defining an upper chamber and a lower chamber therein, a shiftable control rod extending into said housing and having an inner end in said housing and an outer end outside of said housing, a stopper fixed on the inner end of said rod and engageable with said seat for sealing said lower chamber from said upper chamber, said upper nipple and said intermediate nipple being in fluid communication with said upper chamber and said lower nipple being in fluid communication with said lower chamber, said stopper being shiftable between an open position in which said lower chamber communicates with said upper chamber and a closed position on said seat in which said lower chamber is not in communication with said upper chamber; said intermediate nipple having a fluid connection with said conduit to be washed and dried, said upper nipple having a fluid receiving communication with said tank whereby fluid from said tank is conducted through said conduit to wash the latter, said lower nipple having an air receiving communication with said dryer whereby air is forced through said conduit to dry the latter, a two way discharge valve having a fluid receiving connection with said fluid circulating means and when said discharge valve is in one position fluid from circulating means is discharged into said tank, and when said discharge valve is in another position fluid from said circulating means is dumped; and electrical control means including a timer, said control means operative to (1) actuate said water supply means to fill said tank, (2) actuate said fluid circulating means, (3) actuate said drain closing means, (4) shift the positions of said two way valves, and (5) actuate said dryer, all in timed sequence.
