  • the plastic tanks include a threaded drain hole and a draincock with a seal threaded into the drain hole at a predetermined torque to effect good sealing.
  • the draincock is unthreaded from the drain hole to open the drain hole to allow fluid to drain from the tanks and radiator core.
  • the draincock may be of a non-threaded type.
  • An example of such a draincock is disclosed in U.S. Patent No. 4,449,692.
  • the tank has an annular pipe with an enlarged end extending outwardly from the tank and a rotatable plug disposed in the annular pipe having passageways therethrough in order to facilitate draining of the tank.
  • the present invention is a draincock assembly for a container including a receiving member for fluid communication with the container and having a projection therein.
  • the draincock assembly also includes a rotatable draincock being partially disposed in the receiving member having a fluid passageway and a guide slot cooperating with the projection to allow the draincock to be rotated and moved axially.
  • the guide slot has a closed position relative to the projection to prevent the draincock from moving axially and draining fluid through the fluid passageway.
  • the guide slot also has an open position rotated relative to the projection to allow the draincock to move axially and drain fluid through the fluid passageway.
  • a draincock assembly is provided for a container such as a radiator in a motor vehicle to allow fluid to be drained axially from a tank of the radiator.
  • the draincock assembly is non-threaded and does not require torque monitoring.
  • the draincock assembly is injection molded and relatively low in cost.
  • the draincock assembly has a fluid passageway to an internal chamber to drain fluid when the draincock is rotated and moved axially.

  • the draincock 32 is generally cylindrical in shape.
  • the draincock 32 includes an annular base portion 34 extending axially and a plurality, preferably a pair of anti-removal hooks 36 extending axially from the base portion.
  • the anti-removal hooks 36 have a generally 'J' shape.
  • the anti-removal hooks 36 have an arm 38 extending axially and a flange 40 extending radially and axially. The arms 38 flex inwardly when inserted into the aperture 28 of the tank receiving member 18 until the flanges 40 are past the end of the interior portion 20.
  • the arms 38 flex outwardly to their original position and the flanges 40 may engage the end of the interior portion 20 to prevent the draincock 32 from exiting the tank receiving member 18. It should be appreciated that the anti-removal hooks 36 allow the draincock 32 to snap-fit into the tank receiving member 18 and prevent removal therefrom.
  • the draincock 32 has a guide slot 42 extending circumferentially and partially about the base portion 34.
  • the guide slot 42 has an open end 44 at a free axial end of the base portion 34 and extends axially and circumferentially in a generally arcuate path to a closed end 46.
  • the guide slot 42 receives the stop 30 on the tank receiving member 18. It should be appreciated that the guide slot 42 moves relative to the stop 30 as the draincock 32 is rotated.
  • the draincock 32 also includes a recess 48 forming a recessed portion 50 axially adjacent the base portion 34.
  • the recessed portion 50 is generally annular in shape and has a diameter less than a diameter of the base portion 34.
  • the draincock 32 includes a flange 52 extending radially adjacent the recessed portion 50.
  • the flange 52 is annular in shape and has a diameter approximately equal that of the base portion 34.
  • the draincock 32 also has a seal 54 disposed in the recess 48 and about the recessed portion between the flange 52 and the base portion 34.
  • the seal 54 is an O-ring made of an elastomeric material. It should be appreciated that the seal 54 engages the interior portion 20 when the draincock 32 is disposed in the aperture 28 to prevent fluid from passing therebetween.
  • the draincock 32 includes a chamber portion 56 axially adjacent the flange 52.
  • the chamber portion 56 has a diameter less than a diameter of the base portion 34 to form an inner chamber 58 between the draincock 32 and the tank receiving member 18.
  • the chamber portion 56 has at least one, preferably a pair of apertures 60 extending radially therein and communicating with the inner chamber 58.
  • the apertures 60 are generally circular in shape.
  • the apertures 60 also communicate with a passage extending axially to be described. It should be appreciated that the chamber portion 56 is designed to control fluid flow out rearward axially to drain.
  • the draincock 32 includes a top portion 62 axially adjacent the chamber portion 56.
  • the top portion 62 is generally annular and a diameter greater than a diameter of the base portion 34 to be disposed in the cavity 26 of the exterior portion 24.
  • the top portion 62 includes a flash 64 extending radially outward axially adjacent the chamber portion 56 to provide retention of fluid in the inner chamber 58.
  • the flash 64 has a relatively thin thickness to minimize leakage during drainage. It should be appreciated that the flash 64 is optional depending on the application.
  • the top portion 62 also includes a flange 66 extending radially outward at the other end opposite the flash 64 and is adapted to abut the end of the exterior portion 24 of the tank receiving member 18.
  • the flange 66 is generally annular and has a diameter greater than the top portion 62.
  • the top portion 62 also includes a plurality, preferably a pair of hand removal tabs 68 extending radially and axially outwardly from the flange 66.
  • the removal tabs 68 allow the operator to rotate the draincock 32 with their fingers in a relatively easy manner.
  • the top portion 62 includes a projection or barb 70 extending axially from the flange 66.
  • the barb 70 is generally tubular to allow a hose (not shown) to be attached thereto.
  • the top portion 62 includes a fluid passageway 72 extending therethrough from the barb 70 to the chamber portion 56 to fluidly communicate with the apertures 60 thereof.
  • the fluid passageway 72 acts as a rearward axial drain to allow fluid to flow from the inner chamber 58 through the apertures 60 and fluid passageway 72 and exit the barb 70.
  • the draincock 32 is made of a plastic material such as polypropylene and formed as a monolithic structure being integral, unitary and one-piece by conventional injection molding processes.
  • the draincock 32 In operation of the draincock assembly 10, the draincock 32 is disposed in the tank receiving member 18 in a closed position as illustrated in FIGS. 2 and 4. In the closed position, the stop 30 is at the closed end 46 of the guide slot 42 and prevents the draincock 32 from moving axially.
  • the flange 66 of the top portion 62 abuts the end of the exterior portion 24 of the tank receiving member 18. Fluid is prevented from draining through the draincock 32 because the seal 54 prevents fluid from reaching the inner chamber 55.
  • an operator grasps the removal tabs 68 and rotates the draincock 32 to move the guide slot 42 to the open end 44 thereof and the draincock is moved axially by the operator to an open position illustrated in FIG. 3. Fluid is allowed to flow, as indicated by the arrow A in FIG.
  • the draincock 132 eliminates the flash on the top portion 162 and includes a pair of flanges 180 axially spaced and extending radially outwardly adjacent the chamber portion 156.
  • the draincock 132 includes an annular recess 182 disposed axially between the flanges 180 to form a recessed portion 184.
  • the draincock 132 includes a seal 186 disposed in the recess 182 about the recessed portion 184 between the flanges 180.
  • the seal 186 is an O-ring made of an elastomeric material.
  • the seal 186 prevents fluid from passing between the top portion 162 and the tank receiving member 18.
  • the operation of the draincock 132 is similar to that described above for the draincock 32.
