Abstract
Abstract The dosaging device comprises rotary slide valve in the housing of which is arranged a rotatable cylindrical main cock which is combined with an independently rotatable auxiliary cock, both of which are rotatable about the same horizontal axis. The main cock is provided with a plurality of axially alined chambers which open toward the circumference of the cock and are adapted to communicate with an inlet aperture in the housing. Each chamber extends over a sector angle of about 180* along the perimeter of the main cock. In each chamber extends a displacement sector extending over a sector angle of 90* and forming a part of the auxiliary cock whose other part is formed by a shaft about which the main cock is rotatable relatively to the auxiliary cock. The housing has two parallel rows of outlet apertures connectable with the containers which receive the dosages expelled by the cooperation of the two cocks from the chambers in the main cock.

A dosaging device for viscous substances, comprising a cylindrical housing having a substantially horizontal axis, a rotary slide valve member in said housing, a shaft extending through said valve member in concentric relation to said valve member and said cylindrical housing and being freely rotatable in said valve member, at least one chamber in said valve member extending inwardly from the peripheral surface thereof to said shaft and circumferentially through an angle of approximately 180*, a vane in said chamber secured to said shaft and having an axial width substantially equal to that of said chamber and an angular dimension of approximately 90*, said housing having a top inlet opening and two bottom outlet openings spaced from each other circumferentially of said housing, means for intermittently causing rotary reciprocation of said valve member and said shaft with the vane in relation to each other to introduce doses of material into said chamber alternately at one side of said vane and the other and to discharge said doses alternately through said two bottom openings of the housing, a pair of annular sealing means spaced from each other between said valve member and said shaft adjacent each end of said valve member, pairs of correspondingly disposed annular sealing means between said valve member and said housing, inner and outer annular grooves in said valve member disposed between said pairs of sealing means around said shaft and the inside of said housing, respectively, passage means through said valve member interconnecting said inner and outer grooves, and means in said housing for supplying a sealing fluid to said grooves, there being a play of at least 0.1 millimeter between the outer surfaces of said valve member and vane and the inner surface of said housing thereby enabling thorough cleaning of the device by a stream of steam without disassembly of the device.

A dosaging device for viscous substances, comprising a cylindrical housing having a substantially horizontal axis, a rotary slide valve member in said housing, a shaft extending through said valve member in concentric relation to said valve member and said cylindrical housing and being freely rotatable in said valve member, at least one chamber in said valve member extending inwardly from the peripheral surface thereof to said shaft and circumferentially through an angle of approximately 180*, a vane in said chamber secured to said shaft and having an axial width substantially equal to that of said chamber and an angular dimension of approximately 90*, said housing having a top inlet opening and two bottom outlet openings spaced from each other circumferentially of said housing, means for intermittently causing rotary reciprocation of said valve member and said shaft with the vane in relation to each other to introduce doses of material into said chamber alternately at one side of said vane and the other and to discharge said doses alternately through said two bottom openings of the housing, a pair of annular sealing means spaced from each other between said valve member and said shaft adjacent each end of said valve member, pairs of correspondingly disposed annular sealing means between said valve member and said housing, inner and outer annular grooves in said valve member disposed between said pairs of sealing means around said shaft and the inside of said housing, respectively, passage means through said valve member interconnecting said inner and outer grooves, and means in said housing for supplying a sealing fluid to said grooves, there being a play of at least 0.1 millimeter between the outer surfaces of said valve member and vane and the inner surface of said housing thereby enabling thorough cleaning of the device by a stream of steam without disassembly of the device.
