Abstract
Abstract A turbine comprising an outer housing, a rotary casing in the housing and having an inner peripheral surface carrying circumferentially spaced turbine blades, and a radial arm within the rotary casing terminating in a circumferentially oriented nozzle for directing a jet of power fluid under pressure at the turbine blades. The spent power fluid escapes through passages in one end wall of the rotary casing and produces a reactive effect supplementing the nozzle and turbine blade effect. Thus, the invention provides a combination impulse and reaction turbine.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
In a turbine, the combination of: a. an outer housing having axially spaced ends and having an inlet for power fluid under pressure in one of said ends thereof; b. a rotary casing in said housing and rotatable about the axis thereof and having axially spaced ends; c. said casing having an inner peripheral surface carrying circumferentially spaced turbine blades; d. a stationary, generally radial arm within said casing and carried by said housing; e. said arm having a generally radial passage therein; f. said arm having an inlet at its inner end in communication with the inner end of said radial passage; g. inlet passage means connecting said inlet in said arm to said inlet in said one end of said housing; h. nozzle means at the outer end of said arm, and communicating with the outer end of said radial passage, for directing a jet of power fluid under pressure at said turbine blades; i. circumferentially spaced discharge passages in one of said ends of said casing and having outer ends in communication with the interior of said casing adjacent said inner peripheral surface thereof; j. an outlet in said housing; and k. discharge passage means connecting the inner ends of said discharge passages to said outlet in said housing.
Claim 2
Dependent Claim

In a turbine, the combination of: a. an outer housing having axially spaced ends and having an inlet for power fluid under pressure in one of said ends thereof; b. a rotary casing in said housing and rotatable about the axis thereof and having axially spaced ends; c. said casing having an inner peripheral surface carrying circumferentially spaced turbine blades; d. a stationary, generally radial arm within said casing and carried by said housing; e. said arm having a generally radial passage therein; f. said arm having an inlet at its inner end in communication with the inner end of said radial passage; g. inlet passage means connecting said inlet in said arm to said inlet in said one end of said housing; h. nozzle means at the outer end of said arm, and communicating with the outer end of said radial passage, for directing a jet of power fluid under pressure at said turbine blades; i. circumferentially spaced discharge passages in one of said ends of said casing and having outer ends in communication with the interior of said casing adjacent said inner peripheral surface thereof; j. an outlet in said housing; and k. discharge passage means connecting the inner ends of said discharge passages to said outlet in said housing.
Claim 3
Dependent Claim
30 words
A turbine as set forth in claim 1 wherein said turbine blades are so shaped as to deflect the spent power fluid toward said outer ends of said discharge passages.
Claim 4
Dependent Claim
18 words
A turbine according to claim 1 wherein said outlet in said housing is in said one end thereof.
Claim 5
Dependent Claim
21 words
A turbine as defined in claim 3 wherein said discharge passage means includes an annular portion encircling said inlet passage means.
Claim 6
Dependent Claim
35 words
A turbine as set forth in claim 4 wherein said inlet in said housing is located on the axis of said housing and said outlet in said housing is offset radially from said inlet therein.
Claim 7
Dependent Claim
24 words
A turbine according to claim 5 wherein said discharge passage means includes a portion connecting said annular portion to said outlet in said housing.
Claim 8
Dependent Claim
20 words
A turbine as defined in claim 1 wherein said housing provides a sealed, evacuable space in which said casing rotates.
