Abstract:
1. A compressor comprising a valve comprising: (a) a valve body having a poppet valve chamber with an axis running there through and a valve inside surface; (b) a removable seat having a seat sealing surface, a flow restriction surface and an outer-seat surface, the seat located axially within the poppet valve chamber, wherein the seat sealing surface and the flow restriction surface are distinct surfaces each having a different angle relative to the axis; and (c) a poppet having a poppet sealing surface and a second poppet surface each having a different angle relative to the axis, and wherein the poppet sealing surface and the second poppet surface form an intersection, and wherein the location of the poppet is dependent on the flow rate of a fluid through the valve, the poppet being located axially within the poppet valve chamber; wherein the intersection and the flow restriction surface are operable to form a flow restriction zone for fluid flowing therebetween, wherein a poppet-seat interface is created between the seat sealing surface and the poppet sealing surface, the poppet-seat interface being at an angle β of from 20 to 90° to the axis.
