Abrégé

A mechanical seal of the cartridge type. A rotary subassembly includes a sleeve, the sleeve packed against and adapted to be in sealing disposition with a pump shaft of a pump. A stationary subassembly is for attachment to a stuffing box of the pump, the stationary subassembly including a gland, the gland having a front face and a back face and a gland lip extending from the back face. A lip seal is disposed within the gland at the back face below the gland lip, wherein the lip seal concurrently seals and acts as a secondary lubricant within the seal. In addition, a scroll is crimped onto the sleeve of the rotary subassembly at the downshaft end thereof, wherein the scroll includes a spirally-arranged, ridged outer surface.

• F04C 27/00 - Systèmes d'étanchéité dans les pompes à piston rotatif spécialement adaptées pour les fluides compressibles
• F16J 15/324 - Agencements pour graissage ou refroidissement du joint d’étanchéité lui-même
• F16J 15/3256 - Joints d'étanchéité entre deux surfaces mobiles l'une par rapport à l'autre par joints élastiques, p. ex. joints toriques pourvus d’armatures ou de supports avec armatures ou supports rigides comprenant deux éléments d’armature ou de support, individuellement fixés sur chacune des surfaces, p. ex. joints de type cartouche

A mechanical seal of the cartridge type. A rotary subassembly including a sleeve, the sleeve packed against and adapted to be in sealing disposition with a pump shaft of a pump; a stationary subassembly for attachment to a stuffing box of the pump, the stationary subassembly including a gland, wherein the gland has a front face and back face; and, a register defined within the gland front face, the register being an opening shaped to fit over a raised face of the stuffing box, thereby limiting side loading of the seal. In addition, a composite setting piece press-fitted into a bore between the bushing section and the drive collar, thereby allowing the seal to be preset in lieu of a screw or clip.

Classes IPC  ?

• F16J 15/34 - Joints d'étanchéité entre deux surfaces mobiles l'une par rapport à l'autre par bague glissante pressée contre la face plus ou moins radiale d'une des deux parties

A collar for use on a water filtration tank adapter. The collar is formed as a ring adapted to thread onto the tank connection end of the adapter and abut the nut portion between the tank connection end and the pipe end of adapter. An o-ring, square in cross-section, is disposed on a top surface of the collar, offset medially towards the center. This top o-ring is adapted to abut the nut portion of the adapter. Another o-ring, square in cross-section, is disposed on the bottom surface, offset medially away from the center. This bottom o-ring is adapted to abut the tank head upon use. Accordingly, a water-tight seal is formed at the tank connection end and tank head, the collar functioning as both a positive stop and as a substitute for pipe tape.

Classes IPC  ?

• F16L 5/10 - Scellement en utilisant uniquement des segments ou des manchons d'étanchéité
• F16J 15/06 - Joints d'étanchéité entre surfaces immobiles entre elles avec garniture solide comprimée entre les surfaces à joindre
