Abstract
Abstract A machine of the rotary blade type in which a rotor having discal members fixed mounted on its opposite end surfaces is rotatably and eccentrically mounted in a casing. At least a telescopic blade comprising a plurality of blade portions is mounted for sliding motion in a blade groove formed to extend through the rotor and the discal members are formed with grooves for supporting and guiding the telescopic blade. Support means are arranged in two rows on the outsides of the discal members for positioning respective blade portions, the support means being parallel to each other and mounted rotatably. Two telescopic blades can be disposed in two parallel blade grooves formed to extend through the rotor.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
152 words
A machine of the rotary blade type comprising a casing; a rotor rotatably mounted in said casing and disposed eccentrically with respect to the cylindrical inner surface of the casing; at least one telescopic blade mounted for sliding motion in a blade groove formed to extend through said rotor, said telescopic blade comprising a plurality of blade portions telescopically fitted one into another; discal members fixedly mounted on opposite end surface of said rotor and formed with grooves for supporting and guiding said telescopic blades, said casing, said rotor, said discal members and said telescopic blades defining working chambers which undergoes a change in capacity as said rotor rotates; and support means arranged in two rows on the outsides of said discal members for positioning respective blade portions, said support means being parallel to each other and mounted rotatable and concentrically with the cylindrical inner surface of the casing through antifriction means.
Claim 2
Dependent Claim
152 words
A machine of the rotary blade type comprising a casing; a rotor rotatably mounted in said casing and disposed eccentrically with respect to the cylindrical inner surface of the casing; at least one telescopic blade mounted for sliding motion in a blade groove formed to extend through said rotor, said telescopic blade comprising a plurality of blade portions telescopically fitted one into another; discal members fixedly mounted on opposite end surface of said rotor and formed with grooves for supporting and guiding said telescopic blades, said casing, said rotor, said discal members and said telescopic blades defining working chambers which undergoes a change in capacity as said rotor rotates; and support means arranged in two rows on the outsides of said discal members for positioning respective blade portions, said support means being parallel to each other and mounted rotatable and concentrically with the cylindrical inner surface of the casing through antifriction means.
Claim 3
Dependent Claim
53 words
A machine of the rotary blade type as claimed in claim 1, characterized in that said telescopic blades are two in number and disposed for sliding motion in two parallel blade grooves formed to extend through said rotor, said two blades defining therebetween an intermediate chamber which is sealed against the working medium.
Claim 4
Dependent Claim
81 words
A machine of the rotary blade type as claimed in claim 1 characterized in that a gear and a positioning annular groove are provided on the outer peripheral surface of each of said discal members, and a plurality of shafts are provided parallel to the rotor axis for mounting thereon a gear and friction wheel which are adapted to mesh with said gear and said groove on the outer peripheral surface of each discal member for tranSmitting power through said shafts.
Claim 5
Dependent Claim
75 words
A machine of the rotary blade type as claimed in claim 1, characterized in that said rotor is disposed eccentrically with respect to the casing such that the working medium can be prevented from leaking through a position in which the rotor is brought into contact with the inner surface of the casing, and a recess is formed between the blades on the surface of the rotor for allowing the working medium to pass therethrough.
Claim 6
Dependent Claim
77 words
A machine of the rotary blade type as claimed in claim 1, characterized in that ring-shaped airtight rotors are rotatably mounted concentrically with the cylindrical inner surface of the casing and maintained in contact therewith through antifriction means, said airtight rotors being disposed on the lateral sides of the discal members in face-to-face relationship, said airtight rotors being maintained in intimate contact with the tips of the blades or sliders provided on the tips of the blades.
Claim 7
Dependent Claim
69 words
A machine of the rotary blades type as claimed in claim 1, characterized in that means is provided for adjusting the opening and closing of suction and discharge valves and the timing of ignition of electric ignition means or of fuel injection of fuel injection means, whereby the machine can be adapted to perform a four cycle operation or six cycle operation including the cooling cycle and scavenging cycle.
Claim 8
Dependent Claim
54 words
A machine of the rotary blade type as claimed in claim 6, characterized in that two ignition means or two fuel injection means and suction and discharge valves are mounted symmetrically on opposite sides of the contact position of the rotor and the inner surface of casing, whereby the machine can be made self-reversing.
Claim 9
Dependent Claim
54 words
A machine of the rotary blade type as claimed in claim 1, characterized in that two machines are arranged in side-by-side relationship, each of said machines performing a four cycle operation such that one of the working chambers of the two machines are in the explosion cycle for each one of the four cycles.
Claim 10
Dependent Claim
61 words
A machine of the rotary blade type as claimed in claim 1, characterized in that three machines are arranged in side-by-side relationship, each of said machines performing a six cycle operation including the cooling cycle and scavenging cycle such that one of the working chambers of the three machines are in the explosion cycle for each one of the six cycles.
Claim 11
Dependent Claim
47 words
A machine of the rotary blade type as claimed in claim 2, characterized in that packing sliders mounted on the tips of the two parallel blades are telescopically connected together so as to thereby provide a seal to each of the working chambers and the intermediate chamber.
Claim 12
Dependent Claim
24 words
A machine of the rotary blade type as claimed in claim 2, characterized in that a cooling medium is introduced into said intermediate chamber.
