Curved Discharge Silencer for Hermetic Compressor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing refrigerant compressors face space constraints and inefficiencies due to the need for pressure silencers to be positioned close to the outlet valve for optimal damping and minimal heat loss, leading to bulging compressor housings and suboptimal use of space.
Innovation Solution
A pressure silencer design with curved side walls that can nestle around corners or bends of the piston-cylinder unit and electric motor, minimizing space usage within the compressor housing, and featuring a base body with an inlet flange and outlet channel, divided into chambers for enhanced soundproofing and compactness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressure silencer is positioned close to the outlet valve of the piston-cylinder unit, then optimal damping and minimal heat loss are achieved, but the compressor housing becomes unnaturally bulged and space efficiency is reduced
Solution Approach 1:
The pressure silencer is designed with curved side walls that follow the contour of the electric motor, allowing it to nestle into the available space within the compressor housing. This curved geometry enables the silencer to be positioned close to the outlet valve for optimal damping while maintaining a compact overall housing shape without unnatural bulges.
2Volume of moving object
If the pressure silencer is positioned away from the cylinder head, then space within the compressor housing is improved, but damping performance and heat loss reduction are compromised
Solution Approach 1:
The pressure silencer is designed to envelop or nestle around the electric motor and piston-cylinder unit, utilizing the available space within the compressor housing. This nested arrangement allows the silencer to be positioned as close as possible to the outlet valve without increasing the overall housing volume, thereby maintaining both space efficiency and damping performance.
3Volume of moving object
If the compressor housing is miniaturized to increase resource efficiency, then space is saved, but accommodating the pressure silencer close to the outlet valve becomes more difficult
Solution Approach 1:
The pressure silencer features side walls with different curvature characteristics - one side wall is continuously curved to adapt to the cylindrical or dome-shaped wall of the compressor housing, while the other side wall has discontinuous curvature with partial surfaces arranged at angles to nestle against edges or bends of the electric motor. This localized adaptation of geometry allows optimal positioning in miniaturized compressors.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design allows for a space-saving arrangement of the pressure silencer, reducing empty space within the compressor housing while maintaining effective soundproofing and heat management properties.
Implementation Method 1
Pressure silencers are characterized by the fact that a chamber system is formed in the volume of a base body, through which the compressed refrigerant must flow relatively shortly after it has been compressed in order to be able to achieve the desired damping

AI summary
The invention relates to a discharge silencer (6) for a hermetically encapsulated refrigerant compressor (1), which comprises a piston/cylinder unit (4) that compresses a refrigerant and has a compression chamber (3) and which is enclosed by a hermetically sealed compressor housing (2), wherein the compression chamber (3) is supplied with refrigerant coming from an evaporator through a suction silencer (5) and discharges refrigerant compressed by the piston/cylinder unit (4) into a pressure line (7a, b) through the discharge silencer (6). According to the invention, the discharge silencer (6) comprises a main body (8), on which an inlet flange (9) for the refrigerant coming from the piston/cylinder unit (4) is arranged, and an outlet channel (10), through which the refrigerant can be led into a pressure line (7a, b) that supplies a condenser with compressed refrigerant. The main body (8) has four side walls (11, 12, 13, 14), which each have a longitudinal extension and a width extension that is shorter than the longitudinal extension, wherein the two side walls (11, 12) having larger areas are opposite each other and are curved in the same direction when viewed in a direction parallel to the longitudinal extension.
