A mixing apparatus having a mixing chamber which has inlet ports of resin components to be mixed and an outlet port of a mixture thus obtained, comprising a flow varying member which moves across the mixing chamber to selectively occupy a retracted position in which it is retracted from the mixing chamber and a forward position in which the flow varying member interrupts the flow of the resin components to change the directions thereof, an immovable key member which defines a restriction passage together with the flow varying member which occupies the forward position, and a chamber block which is opposed to the flow varying member to laterally move in order to selectively occupy a forward position in which it defines a part of the mixing chamber and a retracted position in which the chamber block defines a flow varying chamber together with the key member and the flow varying member which occupies the forward position.

A mixing apparatus for resin components comprising: a body having a through bore and a plurality of inlet ports for introducing resin components into a mixing chamber portion of said bore, a cleaning member mounted for reciprocal movement in said bore to displace said resin components from said mixing chamber to an outlet port of said bore; a pair of diametrically opposed passages extending through said body and intersecting said through bore between said inlet ports and said outlet port of said through bore, a flow varying member slidably mounted in one of said passages for movement between a retracted position and a forward position, said flow varying member having an end portion which is aligned with said bore in said retracted position and located internally of the other said passage in the forward position, a chamber block slidably mounted in the other said passage for movement between a forward position and a retracted position, said chamber block having a end portion which defines a part of said through bore in said forward position and partially defines a flow varying chamber in said retracted position, and a key member fixed in the other said passage and dividing the other said passage into at least one smaller restriction passage, whereby said flow varying member in said forward position closes said through bore to movement of said resin components and said end portion of said flow varying member cooperates with said end portion of said chamber block to provide a laterally displaced flow varying chamber accessible in the other said passage through said restriction passage for movement of said resin components from said mixing chamber to said outlet of said bore.
