The object of the invention is to provide a chamber for a heating press which can cope well with the height change of a composite material article. In a chamber for a heating press, upper and lower metal flanges 6, 7 are provided between upper and lower press heating plates 1, 2 and an intrusion par
The object of the invention is to provide a chamber for a heating press which can cope well with the height change of a composite material article. In a chamber for a heating press, upper and lower metal flanges 6, 7 are provided between upper and lower press heating plates 1, 2 and an intrusion part 11 is further formed in the lower metal flange. This intrusion part 11 is intruded into the upper metal flange 6 and the gap between the intrusion part 11 and the upper metal flange 6 is sealed by a packing 22 having a lip.

The gear as defined in the claim 1, wherein the tip section of the longer tooth of the driving rotor engages with the concave section of the longer tooth of the driven rotor. 16. The gear as defined in claim 1, wherein the profile of the transition tooth is smoothly connected in series by a cycloid, an arc and involutes. 17. The gear as defined in claim 1, wherein said shorter teeth are formed with involutes. 18. A fluid machine for transferring, compressing or expanding the fluids, including a casing comprising a "8"-shaped housing, an upper end cover and a lower end cover, in which at least one pair of engaging gear-shaped rotors working as one driving rotor and one driven rotor are accommodated in said casing, at least one gas absorbing port or air inlet is provided on said casing, at least one gas discharging port or air outlet is provided on said end covers, said driving rotor and driven rotor are provided with shorter teeth, transition teeth and at least one longer tooth on their pitch circles respectively, wherein the cross-section of said longer tooth is of a hawk beak shape, the profile of said longer tooth is smoothly connected in series by a convex section, a tip section, a concave section, and a leading section, the convex section of the longer tooth projects into the outside of the pitch circle, the two sides of said longer tooth are respectively provided with a transition tooth which adjoins a shorter tooth on the opposite side of said longer tooth, characterized in that said convex section and leading section of said longer tooth are designed with a reasonable contact ratio so that the leading section can enter into engagement in time just before the convex section is out of engagement, or the convex section can enter into engagement in time just before the leading section is out of engagement. 19. The fluid machine as defined in the claim 18, wherein said end covers are in shape of a plate, one of the end covers is provided with an gas outlet in a shape of a section of ring, the gas outlet is located at the side where the driven rotor is provided, the radius of the outer arc of the air outlet is slightly shorter than the radius of the root circle of the shorter teeth of the driven rotor, and the radius of the inner arc of the air outlet is equal to the minimum distance from the leading section of the longer tooth of the driven rotor to the axis of the shaft of the driven rotor. 20. The fluid machine as defined in the claim 18, wherein said upper and lower end covers being in shape of a plate are provided with air outlets in a shape of a section of ring, the air outlets are located at the side where the driven rotor is provided, the radius of the outer arc of the air outlets is slightly shorter than the radius of the root circle of the shorter teeth of the driven rotor, and the radius of the inner arc of the air outlets is equal to the minimum distance from the leading section of the longer tooth of the driven rotor to the axis of the shaft of the driven rotor. 21. The fluid machine as defined in the claim 18, wherein, at a position of closing to the inner surface of the casing, said end covers are provided with at least one concave sliding valve groove in a shape of a section of a ring, one end of the sliding valve groove is communicated with the air outlet, the radii of the inner arc and outer arc of the sliding valve groove are equal to the radii of the inner arc and outer arc of the air outlet respectively, a sliding valve in a shape of a section of a ring is provided on the sliding valve groove, and the radii of the inner arc and outer arc of the sliding valve are equal to the radii of the inner arc and outer arc of the air outlet respectively. 22. The fluid machine as defined in the claim 18, wherein said end covers are in shape of a plate, one of the end covers is provided with an air inlet in a shape of a section of a ring, the air inlet is located at the side where the driving rotor is provided,
