PURPOSE:To make it possible to prevent the rupture of a delivery valve of a compressor by allowing the delivery valve and its valve seat to make surface contact with each other by an absorption part provided on the delivery valve and bringing the opening and closing operation of the delivery valve close to a parallel travelling motion. CONSTITUTION:On the central part of a delivery valve 3, an absorption part 8 is formed into an approximately Z character shape by a folding processing. Even if a compressed substance is intermittently discharged from a discharge opening, the delivery valve 3 is set, although it is opened and closed in responce to the pressure of said compressed substance, in a state approximately parallel to the valve seat 1 surface because of the expansion action of the absorption part 8, so that the delivery valve 3 is arranged to make surface contact with the valve sheet 1, and its local shock is eliminated, preventing the rupture of the delivery valve of the compressor. |
