Abstract
Abstract A dental turbine hand piece has a body, a turbine rotatable in the body about an axis, a light source arranged on the body, and means for current supply to the light source, a magnetic element formed on one of the turbine and the body, and a winding provided on the other of the turbine element in the body, so that during rotation of the turbine and in the body and interaction between the magnetic member and the winding and electric current is generated which is supplied to the light source.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
93 words
A dental turbine hand piece, comprising a body; a turbine rotatable in said body about an axis; a light source arranged on said body; and means for current supply to said light source, said means including a magnetic element formed on one of said turbine and said body, and a winding provided on the other of said turbine and said body, so that during rotation of said turbine element in said body and interaction between said magnetic member and said winding and electric current is generated which is supplied to said light source.
Claim 2
Dependent Claim
93 words
A dental turbine hand piece, comprising a body; a turbine rotatable in said body about an axis; a light source arranged on said body; and means for current supply to said light source, said means including a magnetic element formed on one of said turbine and said body, and a winding provided on the other of said turbine and said body, so that during rotation of said turbine element in said body and interaction between said magnetic member and said winding and electric current is generated which is supplied to said light source.
Claim 3
Dependent Claim
30 words
A dental turbine hand piece as defined in claim 1, wherein said magnetic member is formed on vanes of said turbine element, while said winding is located on said body.
Claim 4
Dependent Claim
31 words
A dental turbine hand piece as defined in claim 1, wherein said turbine has a turbine head which is movable and turnable about an axis of its rear portion by 180°.
Claim 5
Dependent Claim
55 words
A dental turbine hand piece as defined in claim 3, wherein said turbine has a turbine body, said turbine head is mountable with said turbine body by projections so that when said projections are disengaged said turbine head is turnable, and then said projections are automatically engaged to fix a position of said turbine head.
Claim 6
Dependent Claim
23 words
A dental turbine hand piece as defined in claim 1, wherein said turbine is formed as a double turbine having two turbine parts.
Claim 7
Dependent Claim
27 words
A dental turbine hand piece as defined in claim 5; and further comprising means for supplying air directly to vanes to increase a power of said turbine.
