Abstract:
1. A manifold for a refrigeration system, the manifold comprising: a body comprising a bore hole extending through the body, and a plurality of ports including a first process port for adding and removing refrigerant, and a first side port extending generally transverse to the borehole, for mechanical connection thereto; a first ball valve disposed in the body, between the first process port and the first side port, the first ball valve comprising a first ball having a recess that extends generally radially into the ball from an exterior surface of the first ball, and that is aligned with the bore hole through the body, and a first ball port that extends generally radially in the first ball and generally transverse to a radial direction of the recess, from the recess to the exterior surface of the first ball such that the ball port is in fluid communication with the recess, wherein the first ball port narrows to a fine slit from a wide end, the first ball valve moveable between an open position in which the first ball port is aligned with the first side port and the first side port is in fluid connection with the bore hole through the body, and a closed position in which the first ball port is out of alignment with the first side port, wherein the body comprises a first port tube having mechanical connections at each end, one of the mechanical connections comprising the first side port, the first ball valve disposed between the ends of the first port tube and the first ball valve comprises a channel extending therethrough for fluidly connecting the ends of the first port tube when the first ball valve is in the closed position, the channel extending out of communication with the first ball port and the recess of the first ball valve.
