Abstract
Vane compressor comprising a stator, a rotor housed in the stator and provided with a body internally tangent to a side wall of the stator and with a plurality of vanes sliding in respective seats formed in the body of the rotor and pushed in a centrifugal direction to sealingly cooperate with the side wall of the stator, and a lubrication system comprising in combination one or more solid jet nozzles, arranged in the side wall of the stator to direct the solid jet towards the rotor, and at least one axial spray nozzle.
Claims12
Vane compressor comprising:
- a stator (5) having an axis (A) and provided with at least one intake port (21) and at least one delivery port (23),
- a rotor (10) housed in the stator (5) and having an axis (B) parallel to the axis (A) of the stator (5), the rotor (10) being provided with a body (10) internally tangent to a side wall (8) of the stator (5) and with a plurality of vanes (13) sliding in respective seats (14) formed in the body (12) of the rotor (10) and pushed in a centrifugal direction so as to sealingly cooperate with the side wall (8) of the stator (5), the vanes (13) delimiting in pairs with one another a plurality of compartments (17) having different volumes;
- a lubrication system (24) comprising at least one solid jet nozzle (25) arranged in the side wall (8) of the stator (5) to direct the solid jet towards the rotor (10),
- characterised by comprising at least one axial spray nozzle (26) in combination with said at least one solid jet nozzle (25), said at least one axial spray nozzle (26) being configured to inject a spray jet into the compartments (17) in an axial direction with respect to the stator (5) and to the rotor (10).
