Title: Innovations of John J Mullaney
Introduction
John J Mullaney is a notable inventor based in Warwick, RI (US). He has made significant contributions to the field of mechanical seals, holding a total of 3 patents. His innovative designs focus on enhancing the efficiency and reliability of sealing mechanisms in various applications.
Latest Patents
One of his latest patents is the High-speed easy-maintenance split seal. This mechanical split seal features a tapered carbon split seal ring and a silicon carbide split mating ring. The tapered seal ring is compressed by a tapered seal ring shell, which includes a split 'O' ring to provide even force and improved sealing. The shell is biased toward the seal ring by multiple springs retained by a non-split cup. Additionally, the mating ring is supported by a gland that features a split gland packing assembly for compressing packing material onto the shaft. This design allows the seal to be used as a pump seal, which can be cooled by circulation created by the fluid supplied from either the pump input or output.
Another significant patent is the Pressed in anti-rotation lugs for mechanical face seals. This mechanical face seal includes a non-rotatable seal ring and a rotatable mating ring that is biased into rubbing engagement. The non-rotatable seal ring is housed in a stationary housing and is axially biased toward the rotatable mating ring, which is fixed to a rotatable shaft. An anti-rotation member is pressed into the housing and engages with the non-rotatable seal ring to prevent its rotation while allowing axial movement.
