Claim 1
Independent Claim
306 words
In an angle cock, a body having an inlet and an outlet flow passage therethrough, a ball valve member in said body for controlling said flow passage, a bonnet on top of said body having a bonnet portion extending down into a bore formed in said body, said ball valve member being supported by and formed integral with the lower end of said bonnet portion, an overhanging annular lip portion formed around said bonnet, said bonnet having an annular recess formed therein located inward and adjacent said overhanging annular lip portion, an upstanding lip portion formed around the entrance to said body bore engaging said bonnet recess, said overhanging lip portion cooperating with said bonnet recess to form a seal therebetween to prevent entry of foreign substances from outside the valve body into said bore and bonnet portion, said overhanging annular lip radially overlapping said upstanding lip so that said upstanding lip rides in said annular bonnet recess when said bonnet is rotated, an Oring arranged in a second recess in said bonnet portion and in slidable engagement with said body bore, said O-ring being located immediately below both of said lip portions to further provide a seal to prevent entry of foreign substances from outside the valve body as well as prevent leakage outward from inside the valve body, oppositely disposed lugs formed on said bonnet portion, other oppositely disposed lugs formed on said body bore, said bonnet portion and said body bore having recesses formed therein for the reception of said lugs for locking said bonnet and valve member in place in said body bore while permitting rotary movement of said valve member, said lugs and recesses being located below the position of said O-ring and an annular guiding ring formed on said bonnet portion located between said O-ring and said lugs and recesses.
Claim 2
Dependent Claim
306 words
In an angle cock, a body having an inlet and an outlet flow passage therethrough, a ball valve member in said body for controlling said flow passage, a bonnet on top of said body having a bonnet portion extending down into a bore formed in said body, said ball valve member being supported by and formed integral with the lower end of said bonnet portion, an overhanging annular lip portion formed around said bonnet, said bonnet having an annular recess formed therein located inward and adjacent said overhanging annular lip portion, an upstanding lip portion formed around the entrance to said body bore engaging said bonnet recess, said overhanging lip portion cooperating with said bonnet recess to form a seal therebetween to prevent entry of foreign substances from outside the valve body into said bore and bonnet portion, said overhanging annular lip radially overlapping said upstanding lip so that said upstanding lip rides in said annular bonnet recess when said bonnet is rotated, an Oring arranged in a second recess in said bonnet portion and in slidable engagement with said body bore, said O-ring being located immediately below both of said lip portions to further provide a seal to prevent entry of foreign substances from outside the valve body as well as prevent leakage outward from inside the valve body, oppositely disposed lugs formed on said bonnet portion, other oppositely disposed lugs formed on said body bore, said bonnet portion and said body bore having recesses formed therein for the reception of said lugs for locking said bonnet and valve member in place in said body bore while permitting rotary movement of said valve member, said lugs and recesses being located below the position of said O-ring and an annular guiding ring formed on said bonnet portion located between said O-ring and said lugs and recesses.
Claim 3
Dependent Claim
29 words
The angle cock as claimed in claim 1, in which the top of the bonnet has an operating handle attached to it for rotating said ball valve and bonnet.
Claim 4
Dependent Claim
46 words
The angle cock as claimed in claim 1, in which the top of the bonnet is provided with upstanding lugs upon which an operating handle is pivoted, said operating handle adapted for vertical unlocking movement and for rotary movement to operate said bonnet and valve member.
Claim 5
Dependent Claim
46 words
The angle cock as claimed in claim 1, in which the guiding ring forms one wall for the O-ring recess and the opposite side of the ring rests upon the lugs in the body bore to serve as a guide and bearing for the ball valve.
Claim 6
Dependent Claim
55 words
The angle cock as claimed in claim 1, in which the overhanging lip on the bonnet is around the periphery of the bonnet and the upstanding lip lies in the bonnet recess in cooperative sliding engagement therewith, said upstanding lip being arranged on the body and around the upper edge portion of the body bore.
Claim 7
Dependent Claim
57 words
The angle cock as claimed in claim 1, in which the spaces between the oppositely disposed lugs on the bonnet portion and the body bore are protected and sealed off from entry of moisture, dirt and foreign substances by being located in the valve body below the O-ring and the lips around the top of the body.
Claim 8
Dependent Claim
97 words
In an angle cock, a body having a flow passage, an opening in said body communicating with said flow passage, a valve member in said flow passage for controlling flow therethrough, said valve member having a portion extending through said opening, cooperating mating annular flanges on said valve member portion and body for closing said opening, a seal member between said body and valve member portion directly adjacent said mating flanges, and interlocking lugs on said body and valve member portion, positioned between said seal member and flow passage, for locking said valve member in said body.
Claim 9
Dependent Claim
97 words
In an angle cock, a body having a flow passage, an opening in said body communicating with said flow passage, a valve member in said flow passage for controlling flow therethrough, said valve member having a portion extending through said opening, cooperating mating annular flanges on said valve member portion and body for closing said opening, a seal member between said body and valve member portion directly adjacent said mating flanges, and interlocking lugs on said body and valve member portion, positioned between said seal member and flow passage, for locking said valve member in said body.
