摘要： An apparatus is provided for crimping fittings to hose assemblies. A pair of drive rollers are used for rotating a fitting. A pair of deflector rollers are positioned opposite of the drive rollers. A fitting and hose assembly is placed between the drive rollers and the deflector rollers. The deflector rollers and the drive rollers include a raised portion for producing a crimp in the fitting, thereby expeditiously securing the fitting to the hose and providing a leakproof connection.

摘要： A coupler for connecting the service port of a refrigeration fluid-containing system to an exit conduit has a stem threadably for axial movement within the coupling body between a first open position when fully advanced and a second closed position when fully retracted. A plunger axially extends from sealing means in the stem into a service port collar and unseats spring biased sealing means, permitting passage of refrigeration fluid, when the stem is in a substantially fully advanced position and the service port of a refrigeration fluid-containing system is positioned in a service port collar. When the stem is threadably retracted from a substantially fully advanced position, the plunger assumes a retracted position insufficient to unseat the spring biased sealing means and thereby prevents passage of refrigeration fluid.

摘要： A coupler for a refrigeration system easily snaps and locks in position over a service port and securely seals the coupler with respect thereto. A tubular outer body includes a first set of cavities which captures a first set of rotatable spherical balls A tubular inner body is located within the outer body and includes a second set of cavities for capturing second set of rotatable, spherical balls. The inner body includes a recess therein for selectively receiving the first set of balls from said outer body. The inner surface of the inner body defines an interior which includes a spring-loaded plunger. When the coupler is placed over a service port, the barrel of the service port enters the interior of the inner body and the plunger means contacts a spring-loaded ball valve causing it to open. At the same time, the first set of balls drops into a recess in the service port and the inner body moves forward with the service port against the biasing of an inner body spring. Further forward movement of the inner body causes the first set of balls in the outer body to drop into the recess in the outer surface of the inner body. A spring-loaded outer sleeve surrounding the outer body then moves forward over the first set of balls, thereby locking the inner body in position with respect to the outer body. Since the inner body is already sealed with respect to the service port the whole assembly is safety locked in position.
