Abstract
The piston compressor has a cylindrical block with at least one cylinder lining in which a piston moves without making contact. A collecting chamber for leakage gases which escape along the piston is provided at an end of the cylinder liner remote from the compression chamber. The cylinder liner is double walled to form a chamber through which forced coolant can be passed. In addition, an annular space is provided between the cylinder liner and the cylinder block to prevent leaking gas from passing into the cooling water contained in the cylinder block or cylinder liner. Forced cooling results in a good direct cooling of the cylinder liner.
Claims11
A piston compressor comprising a cylinder block;
- a double walled cylinder liner mounted in said cylinder block, said cylinder liner having a first wall defining a bore for reciprocation of a piston therein and a second wall annularly spaced from said first wall to define an annular chamber therebetween for receiving a coolant, said second wall being spaced from a wall of said cylinder block to define an annular space therebetween;
- a collecting chamber in said cylinder block for receiving leakage gas, said collecting chamber being in communication with said bore of said cylinder liner;
- a vent line in said block communicating with said annular space;
- and
- a pressure gauge connected to said vent line.
A piston compressor comprising
- a cylinder block having a recess therein;
- a double walled cylinder liner sealingly mounted in said cylinder block, said cylinder liner having a first wall defining a bore coaxial of said recess to define a compression chamber therewith and a second wall spaced from said first wall to define an annular chamber therebetween, said second wall being spaced from a wall of said cylinder block to define an annular space therebetween sealed from said annular chamber;
- a piston reciprocally mounted in said bore of said cylinder liner;
- a collecting chamber in said cylinder block remote from said compression chamber for receiving leakage gas from between said piston and said first wall of said cylinder liner;
- and
- means for passing a coolant through said annular chamber of said cylinder liner.

- a collecting chamber in said cylinder block for receiving leakage gas, said collecting chamber being in communication with said bore of said cylinder liner;
- a vent line in said block communicating with said annular space;
- and
- a pressure gauge connected to said vent line.
