Embodiment Construction

[0035] The following description of the preferred embodiments is exemplary only and in no way restricts the disclosure and its application or usage. The same or similar reference numerals are used to denote the same components in the respective drawings, and thus the configurations of the same components will not be described repeatedly.

[0036] Although described herein in connection with a scroll compressor, a valve assembly according to the present disclosure is described. However, it will be appreciated that the valve assembly according to the present disclosure is not limited to scroll compressors, but can be applied to any other application requiring restriction of fluid flow. Furthermore, in the following description of the example embodiments, the valve assembly is installed at the central orifice of the diaphragm, however, depending on the location of the orifice (or referred to as the compression mechanism discharge hole) described below, according to the present di...

Abstract

The invention relates to a discharge valve assembly and a scroll compressor. In one aspect, the invention provides a discharge valve assembly. The discharge valve assembly comprises a housing and a movable valve member; the housing is configured as a cylindrical housing including a cylindrical sidewall and defines an interior cavity, the valve member is arranged in the interior cavity, in addition, the housing is provided with a flow passage to fluidly communicate the interior cavity with a discharge space, fluid discharged from a discharge port can be discharged into the discharge space through the flow passage via the interior cavity, the flow passage is provided at the cylindrical sidewall, in addition, the valve member is movable between a first position in which the valve member allows the discharged fluid to be discharged into the discharge space via the interior cavity and the flow passage, and a second position in which the valve member prevents the fluid from the discharge space from flowing back to the discharge port via the flow passage and the interior cavity. The invention provides the discharge valve assembly which can improve reliability and stability and has a noisereduction function.

Description

technical field [0001] The present disclosure relates to a discharge valve assembly and a scroll compressor. In particular, the present disclosure relates to a discharge valve assembly applied to a scroll compressor, and the present disclosure also relates to a scroll compressor configured with such a discharge valve assembly. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Scroll compressors are volumetric compression machines. The compression mechanism of a scroll compressor generally includes a fixed scroll component and a movable scroll component. Vanes of the fixed scroll member and the movable scroll member engage with each other to compress a working fluid (eg, refrigerant). Usually, after the working fluid is introduced into the compression mechanism from the suction port, the working fluid is compressed through the movement of the fixed s...
