用于冷却设备的往复式压缩机
摘要：
一种用于冷却设备(200)的往复式压缩机(100)，所述冷却设备(200)被提供有闭合回路(C)，所述闭合回路(C)具有：主支路(M)，循环的冷却剂的第一流量(X)在所述主支路(M)中进入所述压缩机；以及至少一个第一节能器支路或次级支路(E)，冷却剂的第二流量(X1)在与冷却剂的所述第一流量(X)的压力不同的压力下在所述至少一个第一节能器支路或次级支路(E)中循环，所述压缩机被提供有至少一个汽缸(110)以及在所述至少一个汽缸中在上止点(S)与下止点(I)之间往复移动的至少一个活塞(111)，并且所述压缩机包括：用于使冷却剂的所述第一流量进入的至少一个抽吸导管，以及在所述汽缸的壁中获得的用于使冷却剂的所述第二流量进入的至少一个第一端口(107)，以此方式，所述活塞至少在其进气冲程期间至少部分地暴露所述至少一个第一端口(107)，并且至少在其压缩冲程期间覆盖所述至少一个第一端口，其特征在于，所述至少一个第一端口(107)具有狭缝形状，所述狭缝形状具有基本上横向垂直于所述汽缸的轴(A)的主要尺寸。
摘要（英）：

A reciprocating compressor for a cooling device provided with a closed circuit (C) having a main branch (M), in which a first flow rate (X) of circulating coolant enters in the compressor, and a first economizer branch, or secondary branch (E), in which a second flow rate (X1) of coolant circulates under a pressure different from the pressure of the first flow rate (X) of coolant, the compressor being provided with a cylinder and a piston reciprocatingly moving in the cylinder, between a top dead center (S) and a bottom dead center (I), and having a suction duct for the entrance of the first flow rate of coolant, and a port obtained in the wall of the cylinder for the entrance of the second flow rate of coolant, in such a way that the piston exposes at least in part the first inlet port, at least during its inlet stroke, and covers the port at least during its compression stroke, wherein the first inlet port has a slit shape with the main dimension substantially transverse to the axis (A) of the cylinder.
