Embodiment Construction

[0027] now refer to figure 1 , which schematically shows a new and improved refrigerant hammer eliminator 10 . The refrigerant hammer eliminator 10 includes a housing 12 . The housing 12 includes an internal compartment 14 . In the embodiment shown, said internal compartment 14 communicates with the refrigerant line L upstream of the shut-off valve V through an open end 15 . Piston 16 is received in housing 12 . The piston 16 divides the inner compartment 14 into a first chamber 18 and a second chamber 20 . In the illustrated embodiment, the piston 16 includes a hemispherical face 21 and two piston rings 22 for providing a smooth sliding action along the inner wall of the housing 12 .

[0028] A damping mechanism, generally indicated at 24 , is provided to slow displacement of the piston 16 within the housing 12 . In the illustrated embodiment, the damping mechanism 24 is arranged in the second chamber 20 .

[0029] The damping mechanism 24 is preferably a variable dampi...

Abstract

A refrigerant hammer arrestor includes a housing having an internal compartment communicating with a refrigerant line, a piston received in the housing and dividing the internal compartment into a first chamber and a second chamber and a damping mechanism to dampen displacement of the piston within the housing. Various refrigerant loops are also described incorporating a refrigerant hammer arrestor.

Description

technical field [0001] This document relates generally to climate control systems, and more particularly to a refrigerant hammer arrestor and a refrigerant circuit including the refrigerant hammer arrestor. Such technology may be incorporated into motor vehicles. Background technique [0002] A fluid hammer is a pressure surge or wave caused when a fluid in motion is suddenly forced to stop or change direction. For example, a closed valve in a fluid system, such as a refrigerant circuit, can cause a fluid hammer pulse to occur. The compressing action of the compressor in the refrigerant circuit can also generate pressure pulses in the system. These pressure waves have the potential to create noise and vibration problems that can be annoying to motor vehicle drivers and, in some cases, can lead to durability problems. In some cases, a pressure pulse can trip the pressure sensor on the compressor and force the compressor to shut down prematurely. [0003] This document is ...
