The valve has a sealing surface which engages the central portion around its whole circumference in liquid sealing relationship a pair of integral lever arms transmit a shapedeforming force to the flexible outer portion to lift a portion of the sealing surface out of contact with the rigid cylinder, to permit passage of liquid through said valve.</p> |
