| 摘要 |
An orifice assembly for emitting a stream of fluid under high pressure has an orifice member having an aperture therein through which a high pressure fluid is emitted, a support member on which the orifice member is disposed, the support member providing support for the orifice member and being flexible in response to the application of high pressure fluid to the orifice member and having a passageway therein in communication with the aperture in the orifice member. Because of the flexing of the support member on which the orifice member is disposed, the orifice member is allowed to move in response to the application of the high pressure fluid, reducing damage to the orifice member due to shock from the high pressure fluid, particularly when cycling on and off. A housing has an opening for receiving the orifice member and support member therein, and a retainer holds the orifice member and support member in the housing.
