Abstract: A minimum pressure valve (10) comprising a housing (17) with the valve inlet (11) and the valve outlet (12) connected with each other by a chamber and connecting space (22a, 22b), the minimum pressure valve (10) also comprising a valve body (21) set up in a chamber (20) moveably between a closed position in which the valve inlet (11) is closed and an open position in which the valve inlet (11) is open, the minimum pressure valve (10) also comprising components which are provided with a seal and/or sliding parts (24, 26, 30), whereby a subassembly (22) of the minimum pressure valve (10) can be disassembled and/or assembled through an opening (31) in the housing (17).

Abstract: Unloader for a compressor, said unloader (1) comprising a housing (2) with an inlet (3) and an outlet (4), and whereby the unloader (1) is further provided with a piston rod (5) which is arranged moveably in a reciprocating manner in the housing (2), whereby on one end (5a) of the piston rod (5) a valve (7) is provided to be able to close the outlet (4) and whereby on the other end (5b) of the piston rod (5) a piston (8) is arranged, the piston being arranged moveably in a reciprocating manner in a thereto provided cavity (9) of the unloader (1), said cavity (9) being at least partially delimited by a lid (10) which is provided on the housing (2) and which is also part of the unloader (1), whereby sealing means (11) are provided for the leakage-free movement of the piston (8) in said cavity (9), whereby the cavity (9) in which the piston (8) is arranged moveably in a reciprocating manner is provided at least partially in the lid (10).

Abstract: Oil-injected screw compressor installation including a frame or underframe (5 2), a screw compressor element (3), electrical cabinet (6), oil separator vessel (5) and an air-cooled cooling module (8), with as characteristic that on one side (2a) of the frame (2), the screw compressor element (3) is placed horizontally and with the electrical 10 cabinet (6), the oil separator vessel (5) and the aircooled cooling module (8) being placed on the other side (2b) of the frame (2), with the cooling module (8) being placed such that this is perpendicular to the compressor element (3) and the air (9) sucked in by the cooling module 15 (8) will flow between the electrical cabinet (6) and the cooling module (8).
