DEFINITION

Classification: 415/55.2

Having specific means to deflect working fluid in

regenerative passage:

(under subclass 55.1) Device wherein particular significance is attributed to a working fluid* guiding vane* or other means which guides the working fluid passing within the (regenerative) channel portion.

(1) Note. Working fluid flow guides positioned at the working fluid entrance or exit to the (regenerative) channel portion are included in this subclass.
