Release collar for coupling assembly

摘要

An apparatus for of reliably separating the male and female members of a coupling that may be used in high pressure conditions. A release collar ( 201 ) has an actuator ( 301 ), a release sleeve flange ( 303 ), and a ring ( 305 ). The actuator ( 301 ) is thinner than those utilized in known release sleeves, and may be advantageously located in closer proximity to the male member ( 101 ) than to the female member ( 103 ), such that the actuator may radially expand between the male and female members. The actuator ( 301 ) may be comprised of a cylindrical annulus and/or fingers disposed in a circular pattern. The ring ( 305 ) may have a lip ( 307 ) that allows the release collar ( 201 ) to remain with the female member ( 103 ).
