According to embodiments described in the specification, a brewing chamber for a beverage machine is provided comprising a housing having upper and lower ends and a channel extending between the upper and lower ends; an outlet portion of the channel configured to direct liquid towards the lower end; an extraction member extending from an inner surface defined by a wall of the outlet portion, the extraction member having an upper penetrating end for penetrating a cartridge and an anchoring end abutting the wall; the extraction member further having guide means for guiding liquid from the penetrating end onto the inner surface. The brewing chamber can include at least one spring coupled to the housing at the inlet end, the at least one spring receivable within a pocket of a support insert supporting a cartridge. The spring centers the support insert over the housing and facilitates ejection of the support insert.

1. A brewing chamber comprising: a housing having inlet and outlet end and a channel extending between the inlet and outlet ends; the channel defining an inner surface of the housing extending from the inlet end to the outlet end and configured to direct liquid to the outlet end; a cartridge penetrating extraction member extending into the channel from the inner surface, the cartridge penetrating extraction member having an open penetrating end for penetrating a cartridge and a closed anchoring end abutting the inner surface of the housing intermediate the inlet and outlet ends and above the outlet end of the housing; the cartridge penetrating extraction member further having a substantially tubular member extending between the open penetrating end and the closed anchoring end for guiding liquid from the open penetrating end directly onto the inner surface of the housing above the outlet end of the housing; the tubular member having a chase or other guide means extending along the tubular member from the open penetrating end to a point intermediate the open penetrating end and the closed anchoring end,wherein the substantially tubular member of the cartridge penetrating extraction member is substantially cylindrical and extends between the open penetrating end and the closed anchoring end of the cartridge penetrating extraction and the guide means has at least one longitudinal groove on the surface of the substantially tubular member; the at least one longitudinal groove extending from the open penetrating end towards the closed anchoring end. 2. The brewing chamber of claim 1, wherein the extraction member extends substantially vertically from the inner surface. 3. The brewing chamber of claim 1, wherein the guide means of the cartridge penetrating extraction member comprises a longitudinal slot in a side of the tubular member. 4. The brewing chamber of claim 3, wherein the tubular member is obstructed between the closed anchoring end of the cartridge penetrating extraction member and a lower end of the longitudinal slot. 5. The brewing chamber of claim 1, wherein the cartridge penetrating extraction member is integrally formed with the inner surface of the housing. 6. The brewing chamber of claim 1, wherein the cartridge penetrating extraction member is integrally formed with the housing. 7. The brewing chamber of claim 1, further comprising support means for supporting the cartridge within the channel. 8. In a brewing chamber having a housing including an inlet and outlet end and a channel extending between the inlet and outlet ends, an outlet portion of the channel defining an inner surface extending from the inlet end to the outlet end and configured to direct liquid towards the outlet end, wherein the improvement comprises a cartridge penetrating extraction member having: (a) a closed anchoring end abutting the inner surface of the housing; and(b) a substantially tubular member extending upwardly from the closed anchoring end to an open penetrating end for penetrating a cartridge, the substantially tubular member having a chase or groove to guide liquid from the open penetrating end and the chase or groove directly onto the inner surface of the housing,wherein the substantially tubular member of the cartridge penetrating extraction member is substantially cylindrical and extends between the open penetrating end and the closed anchoring end of the cartridge penetrating extraction and the guide means has at least one longitudinal groove on the surface of the substantially tubular member; the at least one longitudinal groove extending from the open penetrating end towards the closed anchoring end. 9. The extraction member of claim 8, wherein the chase on the substantially tubular member comprises a longitudinal slot in a side thereof. 10. The extraction member of claim 8, wherein the substantially tubular member extends substantially vertically from the closed anchoring end to the open penetrating end. 11. The extraction member of claim 8, wherein the substantially tubular member is substantially cylindrical and the groove is at least one longitudinal groove on the surface thereof, the at least one longitudinal groove extending from the open penetrating end towards the closed anchoring end.
