Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
221 words
An apparatus for mixing two fluid components and discharging the mixture thereof, comprising: housing means including a housing member defining a mixing chamber having an end mixture-discharge port; a pair of lateral inlet ports formed in said housing member and opening toward said chamber, while being connectable to respective sources of fluid components to be mixed; a pair of lateral recirculation ports formed in said housing member and spaced from said inlet ports; and a control slide member longitudinally extending within said housing means and shiftable within said chamber between a first position affording communication between said inlet bores and said chamber, and a second position blocking such communication, said control slide member being formed with respective bypass channels in mutually spaced relationship respectively connecting each of said inlet ports with an associated recirculation port in said second position, said slide member being provided with longitudinal grooves opening toward the other member between said bypass channels for receiving said mixture and forming seals therefrom between confronting surfaces of the slide member and the housing member, said grooves being formed in the said surface of said slide member and extending from an end of said slide member turned toward said mixture-discharge opening over the length of the slide member to a location just short of the other end of said slide member.
Claim 2
Independent Claim
221 words
An apparatus for mixing two fluid components and discharging the mixture thereof, comprising: housing means including a housing member defining a mixing chamber having an end mixture-discharge port; a pair of lateral inlet ports formed in said housing member and opening toward said chamber, while being connectable to respective sources of fluid components to be mixed; a pair of lateral recirculation ports formed in said housing member and spaced from said inlet ports; and a control slide member longitudinally extending within said housing means and shiftable within said chamber between a first position affording communication between said inlet bores and said chamber, and a second position blocking such communication, said control slide member being formed with respective bypass channels in mutually spaced relationship respectively connecting each of said inlet ports with an associated recirculation port in said second position, said slide member being provided with longitudinal grooves opening toward the other member between said bypass channels for receiving said mixture and forming seals therefrom between confronting surfaces of the slide member and the housing member, said grooves being formed in the said surface of said slide member and extending from an end of said slide member turned toward said mixture-discharge opening over the length of the slide member to a location just short of the other end of said slide member.
Claim 3
Dependent Claim
30 words
The apparatus defined in claim 1, further comprising an annular transverse groove formed in the said surface of said slide member at said other end and interconnecting said longitudinal grooves.
Claim 4
Dependent Claim
31 words
The apparatus defined in claim 1, further comprising at least one annular transverse groove formed in said surface of said control slide at said one end and interconnecting said longitudinal grooves.
Claim 5
Dependent Claim
19 words
The apparatus defined in claim 1, wherein said grooves are formed as flats extending longitudinally along said slide member.
Claim 6
Dependent Claim
19 words
The apparatus defined in claim 4, wherein said chamber is cylindrical and said slide member has a polygonal cross-section.
Claim 7
Dependent Claim
50 words
The apparatus defined in claim 1, wherein said chamber and said slide member are of rectangular cross-section whereby said slide member has four sides, said channels being provided in at least one pair of opposite sides and said grooves being provided at least in the other pair of opposite sides.
Claim 8
Dependent Claim
30 words
The apparatus defined in claim 1, further comprising respective pumps communicating with said inlet ports for delivering said components thereto and having intake sides connected with the respective recirculation ports.
