Abstract
Abstract The valve member is composed of a cylindrically-shaped body portion having an open longitudinally extending channel for conducting product material from a supply pipe to a discharge pipe and registerable in one rotative position of the valve member with a row of openings at the bottom of loading cylinders provided with pistons. The entry end of the channel is in communication with a product material supply pipe and the discharge end of the channel is in communication with a material discharge pipe. The valve body portion is also provided with a row of transverse passages which in another rotative position of the valve member connects the cylinder openings with product material discharge openings. The entry and discharge ends of the channel are configured to provide an uninterrupted free flow of product material from the supply pipe to the discharge pipe throughout the reciprocative movements of the valve member between the said two rotative positions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
313 words
A valve member for product material depositing apparatus composed of a housing provided with a row of cylinders, each having a bottom opening and a piston mounted for reciprocating movement therein, and provided with a circular chamber located below said cylinders and having its longitudinal axis extending in parallelism with a horizontal line passing through the centerlines of the row of cylinders, the bottom openings of said cylinders being in communication with said chamber, the housing also being provided with a row of discharge openings equal in number to said bottom openings along the length of and communicating with the circular chamber, and said apparatus including first means in communication with one portion of the circular chamber for continuously supplying product material, and second means in communication with another portion of the circular chamber, in spaced relation to said one portion thereof, for discharging excess product material, the valve member being locatable in said circular chamber and having a substantially cylindrical body portion extending between said first and second means and provided with an open longitudinally extending channel for conducting product material from said first means to said second means, said valve member being rotatable to one position in the circular chamber to bring said channel into registry with the cylinder bottom openings, a row of passages equal in number to said bottom and discharge openings extending transversely through said body portion and arranged along a line spaced from and parallel to said channel, said valve member being rotatable to another position in the cylindrical chamber to bring the ends of said passages into registry with said bottom and discharge openings, the entry and discharge portions of said channel being configured to enable an uninterrupted free flow of product material from said first means to said second means throughout the reciprocative rotative movements of said valve member between said one and other positions.
Claim 2
Dependent Claim
313 words
A valve member for product material depositing apparatus composed of a housing provided with a row of cylinders, each having a bottom opening and a piston mounted for reciprocating movement therein, and provided with a circular chamber located below said cylinders and having its longitudinal axis extending in parallelism with a horizontal line passing through the centerlines of the row of cylinders, the bottom openings of said cylinders being in communication with said chamber, the housing also being provided with a row of discharge openings equal in number to said bottom openings along the length of and communicating with the circular chamber, and said apparatus including first means in communication with one portion of the circular chamber for continuously supplying product material, and second means in communication with another portion of the circular chamber, in spaced relation to said one portion thereof, for discharging excess product material, the valve member being locatable in said circular chamber and having a substantially cylindrical body portion extending between said first and second means and provided with an open longitudinally extending channel for conducting product material from said first means to said second means, said valve member being rotatable to one position in the circular chamber to bring said channel into registry with the cylinder bottom openings, a row of passages equal in number to said bottom and discharge openings extending transversely through said body portion and arranged along a line spaced from and parallel to said channel, said valve member being rotatable to another position in the cylindrical chamber to bring the ends of said passages into registry with said bottom and discharge openings, the entry and discharge portions of said channel being configured to enable an uninterrupted free flow of product material from said first means to said second means throughout the reciprocative rotative movements of said valve member between said one and other positions.
Claim 3
Dependent Claim
37 words
A valve member as defined in claim 1, in which said open channel is formed by a recessed, concavely-shaped wall having a width between the outer edges thereof substantially greater than the diameter of said bottom openings.
Claim 4
Dependent Claim
83 words
A valve member as defined in claim 1, in which the entry portion of said channel comprises an arcuate crescent-shaped wall, the upper concave edge of which is in juncture with the forward end edge of the main portion of said channel and the lower convex edge of which terminates at the forward end face of said body portion, said wall forming an enlarged entry chamber having a radial dimension greater than the radial dimension of the discharge end of said first means.
Claim 5
Dependent Claim
93 words
A valve member as defined in claim 1, in which the discharge portion of said channel comprises two arcuately-shaped walls disposed in radial side-by-side relation so that their inner edges join to form an arcuate ridge in substantial alignment with the bottom of the main portion of the channel, and the outer edges thereof extend to the periphery of the valve body portion, one of said walls being in alignment and forming an extension of the channel wall, and the other of said walls being in substantial alignment with said row of passages.
Claim 6
Dependent Claim
41 words
A valve member as defined in claim 1, in which said row of passages are offset from the longitudinal centerline of said valve body portion and such centerline is located between said row of passages and the bottom of said channel.
Claim 7
Dependent Claim
68 words
A valve member as defined in claim 1, in which said body portion has a shaft member integrally connected thereto and the outer end face of which is visible when said valve member is assembled in sAid apparatus, said end face of said shaft member being provided with means to indicate at all times the position of said valve member relative to the bottom openings of said cylinders.
