Embodiment Construction

[0016] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] An oil pump inlet and outlet structure, such as figure 1 As shown, it includes an oil return layer 101, an oil pressure layer 102, a separator 103, and a safety valve 104. The oil return layer 101, the separator 103, and the oil pressure layer 102 are sequentially connected by bolts, and the safety valve 104 is installed on the oil pressure layer 102 through threads to discharge oil end; the oil return layer 101 is integrated with an oil inlet cavity, and the oil pressure layer 102 is integrated with an oil return layer oil outlet cavity 9, and the oil return layer 101 transports oil to the Back to the oil layer oil chamber 9.

[0019] The oil return layer 101 is also integrated...

Abstract

The invention provides an oil inlet and return structure for an oil pump, which comprises an oil return layer, an oil pressing layer, a partition and a safety valve, wherein the oil return layer, thepartition and the oil pressing layer are fixedly connected; the safety valve is arranged at the oil outlet end of the oil pressing layer; an oil inlet cavity is integrated on the oil return layer; anoil return layer oil outlet cavity is integrated on the oil pressing layer; and the oil return layer transports oil to the oil return layer oil outlet cavity through an oil outlet formed in the partition. The oil inlet and return structure has the advantages: (1) the oil inlet oil cavity is integrated with a pump body of the oil pump, and useless space of the pump body of the oil pump is fully used, so that high integration and compactness design of the oil pump structure is realized, and the size of the oil pump is reduced; and (2) the safety valve is installed at the oil pressing layer, andis used for discharging engine oil for protecting the oil pump when the outlet pressure of the oil pressing layer of the oil pump is too high.

Description

technical field [0001] The invention belongs to the technical field of engine oil pumps, and in particular relates to an oil inlet and return structure of an engine oil pump. Background technique [0002] For dry-type oil sump diesel engines, since the engine oil pan is not integrated with the oil tank, in order to ensure that the oil can be sucked back to the oil tank in time when the engine is tilted, the dry-type oil sump diesel engine needs a special oil return pump. for oil extraction. [0003] Generally, the oil return pump needs to have a separate oil inlet and outlet pipeline, which is used to pump the oil from the front and rear oil sumps on the oil pan back to the oil tank. Therefore, the pipeline of the oil return pump of the existing dry oil sump diesel engine oil return pump is relatively complicated and occupies a large space. Contents of the invention [0004] In view of this, the present invention aims to propose an oil inlet and return structure of the e...
