Title:
EXHAUST VALVE
Document Type and Number:
Japanese Patent JPS61266882
Kind Code:
A
Abstract:
PURPOSE:To obtain a uniform exhaust characteristic at a substantially constant speed irrespective of the degree of pressure in an accumulator chamber, by providing such an arrangement that the opening area of a vent hole is made to be large under a high pressure while to be small under a low pressure. CONSTITUTION:A vent hold 5 is formed in the center section of a partition wall 3 in an exhaust valve 1. Further, a support member 7 having therein an exhaust passage 6 supports a resistance section 4. The partition wall 3 is formed of resilient materials such as, for example, rubber, and the to variations in pressure within a band, the opening area of the vent hold 5 is made to be large under a high pressure while to be small under a low pressure. With this arrangement, a substantially uniform exhaust speed may be obtained irrespective of the degree of pressure in the accumulating chamber.
