Abstract
A reciprocating compressor comprising a cylinder and a piston dividing the cavity in the cylinder into a first and a second chamber being connected through respective suction valve systems and discharge valve systems to a suction duct and a discharge duct. The suction and discharge valve systems each including a housing defining a valve chamber and a valve body, whereby the compressor is further provided with a vessel defining a volume in fluid connection with a valve chamber of one of the discharge valve systems by a conduit.
Claims9
A reciprocating compressor comprising:
- a cylinder with a cavity therein;
- and
- a reciprocating moveable arrangement comprising a piston and a piston rod and driving means configured to move said arrangement into reciprocating motion,
- said piston dividing said cavity into a first and a second chamber,
- each of said first and second chambers being connected through a respective at least one suction valve system and at least one discharge valve system to a suction duct and a discharge duct,
- said at least one suction valve system and said at least one discharge valve system each comprising a respective housing defining a valve chamber and a valve body, the valve chamber having a first side in direct fluid communication with one of said first and second chamber and a second side and the valve body being moveable between a first, closed position in which the one of said first or second chambers is fluidly disconnected from said valve chamber, and a second, open position in which said first or second chamber is in fluid communication with said respective valve chamber,
- wherein the second side of said valve chamber of said at least one discharge valve system is directly connected to the discharge duct,
- wherein said compressor is further provided with a vessel, the vessel comprising a housing formed as a mainly cylindrical receptacle closed off at one end with a bottom wall, the vessel having a fixed and defined volume, said volume being in direct and continuous fluid connection with the valve chamber of said at least one discharge valve system by a conduit in a way such that compressed fluid does not flow through the vessel to the discharge duct;
- wherein said conduit connecting the discharge valve chamber to said volume in said vessel is made in the shape of a straight tube extending with one end in said discharge valve chamber and with the other end inside said vessel.
