Embodiment Construction

[0028] refer to figure 1 , the compressor unit indicated generally by 1 includes a vane compressor 2 and an electric motor 3 . The compressor unit shown is preferably used as an on-board compressor of a motor vehicle such as a truck, but the invention is not limited to this application and can be applied to compressors of any power and size for vehicular or industrial applications.

[0029] The electric motor 3 , shown for simple reference, is not further described as it is not part of the invention.

[0030] Figure 2 to Figure 9 The compressor 2 shown in is provided with a casing 4 formed by a middle part defining a stator 5 of the compressor 2 , a front cover 6 and a rear flange 7 for connection to an electric motor 3 . The front cover 6 and the flange 7 are fixed on axially opposite parts relative to the stator 5 by means of a plurality of screws 11 .

[0031] The stator 5 is provided with side walls 8 ( Figure 5 ).

[0032] Compressor 2 also includes a rotor 10 of s...

Abstract

Vane compressor comprising a stator (5), a rotor (10) housed in the stator (5) and 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 to sealingly cooperate with the side wall (8) of the stator (5), and a lubrication system (24) comprising in combination one or more solid jet nozzles (25), arranged in the side wall (8) of the stator (5) to direct the solid jet towards the rotor (10), and at least one axial spray nozzle (26).

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Italian Patent Application No. 102017000086572 filed on July 27, 2017, the disclosure of which is incorporated by reference. technical field [0003] The invention relates to a vane compressor. Background technique [0004] The known vane compressor comprises a stator provided with an inlet and a delivery port; a rotor housed eccentrically in the stator, internally tangent to the side wall of the stator and provided with a plurality of vanes sliding on the rotor and in sealing engagement with the stator; and a lubrication system comprising a plurality of mutually aligned Solid Jet nozzles arranged in the sidewall of the stator to direct the continuous jet towards the rotor. [0005] The oil jet provided by the nozzle serves three purposes: [0006] – Lubrication of the relative sliding areas between the blades and the rotor body, between the blade heads and the stator barrel, and...
