Abstract

Male fluid couplers (14) are attached to a control valve (94) mounted in a holder (96). Female fluid couplers (16) have their sleeve members (72) held in an aperture (108) in a sleeve member retainer (110) by snap rings (112). Lever arms (122 and 124) are attached to the sleeve member retainer (110) by pins (126 and 128). Pins (134 and 135) on the lever arms enter slots (136) in the male holder (96). Movement of the lever arms (122 and 124) moves the female couplers (16) into engagement with the male fluid couplers and allows locking balls (40) to move into locking ball grooves (38). Upon release of the handle (130), the spring (80) moves the sleeve member (72) in a position locking balls (40) in the grooves (38). Movement of the handle (130) in the opposite direction moves the sleeve members (72) into position to release the balls (40) from the grooves (38). Continued movement of the handle (130) moves the female couplers (16) from engagement with the male couplers (14).

Dependent claims

A coupler connecting mechanism for simultaneously connecting a plurality of male fluid couplers, each having a tubular body with an outer surface, an end surface and a locking ball groove recessed into the outer surface and spaced from the end surface, to a plurality of female fluid couplers, each having a cylindrical housing with a male coupler receiving bore, a plurality of locking ball passages through the cylindrical housing, a locking ball mounted in each locking ball passage, a sleeve member slidably supported by and surrounding a portion of the cylindrical housing and having an inside land that holds the locking balls in positions in which the locking balls extend radially into the male coupler receiving bore for engaging said locking ball groove, a first locking ball release recess in the sleeve member on a first side of the land, a second locking ball release recess in the sleeve member on a second side of the land and a spring assembly mounted on the cylindrical housing that biases the inside land on the sleeve member toward a position in which the land holds the locking balls extending radially into the male coupler receiving bore and away from positions in which the first or second locking ball release recesses are in alignment with and can receive locking balls, comprising:

a male fluid coupler holder attached to and holding a plurality of male fluid couplers in fixed positions relative to each other;
a female fluid coupler sleeve member retainer attached to and holding the sleeve member of each of said plurality of female couplers in a fixed position relative to each other;
and
a lever pivotally connected to the female fluid coupler sleeve member retainer and having a first lever reaction surface engagable with a first holder reaction surface on said male fluid coupler holder to move the coupler sleeve members toward the male fluid couplers, slide the coupler sleeve members relative to the locking ball passages and move the first locking ball release recess into a position to receive the locking balls and move the female fluid couplers and the male fluid couplers into engagement with each other upon movement of the lever in one direction and having a second lever reaction surface engagable with a second holder reaction surface on said male fluid coupler holder to move the coupler sleeve members away from the male fluid couplers, slide the coupler sleeve members relative to the locking ball passages and move the second locking ball release recesses into a position to receive the locking balls and move the male fluid couplers and the female fluid couplers out of engagement with each other upon movement of the lever in another direction.

A coupler connecting method for simultaneously connecting a plurality of male fluid couplers, each having a tubular body with outer surface, an end surface and a locking ball groove recessed into the outer surface and spaced from the end surface, to a plurality of female fluid couplers, each having a cylindrical housing with a male coupler receiving bore, a plurality of locking ball passages through the cylindrical housing, a locking ball mounted in each locking ball passage, a sleeve member slidably supported by and surrounding a portion of the cylindrical housing and having an inside land that holds the locking balls in positions in which the locking balls extend radially into the male coupler receiving bore, a first locking ball release recess in the sleeve member on a first side of the land, a second locking ball release recess in the sleeve member on a second side of the land and a spring assembly mounted on the cylindrical housing that biases the inside land on the sleeve member toward a position in which the land holds the locking balls and away from positions in which the first or second locking ball release recesses are in alignment with and can receive locking balls, comprising the method steps of:

a. holding a plurality of the male fluid couplers in fixed positions relative to each other;
b. mounting a plurality of the female fluid coupler sleeves in a female coupler sleeve member retainer plate;
c. placing the female fluid coupler sleeve member retainer plate in a position adjacent to the male couplers with the male couplers in alignment with the male coupler receiving bores in the female fluid couplers;
d. moving each female coupler sleeve relative to the cylindrical housing to a position which allows the retainer balls to enter the first locking ball release recess in the sleeve member;
e. forcing the female coupler sleeve member retainer plate and the female fluid couplers into full engagement with the male fluid couplers;
f. releasing pressure on the coupler sleeve member retainer plate to allow the spring assembly of each female fluid couple member to move the sleeve member relative to the cylindrical housing and force the locking balls out of the first locking ball release recesses and into the locking ball grooves to lock each of the male fluid couplers to one of the female couplers;
g. forcing the fluid coupler sleeve member retainer plate away from the male couplers to move the sleeve members relative to the cylindrical housing and free the retainer balls to move from the locking ball grooves and into the second locking ball release recesses;
h. continuing movement of the fluid coupler sleeve member retainer plate away from the male fluid couplers until the male and female fluid couplers are completely disengaged;
and
i. moving the fluid coupler sleeves relative to the cylindrical housing to force the locking balls from the second locking ball release recesses and position the lands of the fluid coupler sleeves to hold the locking balls in positions in which each locking ball extends into the male coupler receiving bore.
