Embodiment Construction

[0058] Figure 1 to Figure 11 A modular motor-pump unit 1 according to a first embodiment is shown. Figure 13 to Figure 22 A modular motor pump unit 100 according to a second embodiment is shown. Hereinafter, first, the modular motor pump unit 1 will be described in detail according to the first embodiment.

[0059] The motor pump unit 1 according to the first embodiment has an outer housing 2 with a connecting portion 6 on the outer periphery. The connection part 6 has a pressure connection and a return hydraulic fluid connection. The outer housing 2 is, for example, a gravity die-cast part made of light metal, such as aluminum or an aluminum alloy. A transverse wall 16 with a plurality of axial through holes 26 is arranged in the outer housing 2 having a stator plug seat 32 to accommodate a stator 33 of the electric motor 4 . The electric motor 4 drives a pump element 5 fixed in the outer housing 2 in a conventional manner, so that hydraulic fluid is pumped from a hydra...

Abstract

The invention relates to a modular motor pump unit (1) comprising: an outer housing (2) having two open ends (2S, 2P) and two a housing cover (3S, 3P); at least one electric motor (4) arranged in said outer housing (2); at least one pump element (5) arranged in said outer housing (2) and which can be provided by said outer housing (2) driven by the motor (4); and at least one connecting portion (6) arranged on the outer side of the outer casing (2). The outer housing (2) forms a hydraulic fluid reservoir (7), and a pressure channel (8) extends from the pump element (5) to the connecting portion (6). A return channel (9) extends from the connecting portion (6) to the interior of the outer housing (2). An additional housing (10) is arranged between the outer housing (2) and at least one housing cover (3S, 3P). A heat exchanger element (11) is arranged in said additional housing (10), and said return channel (9) is connected to said additional housing (10), and said additional housing (10) is connected to said hydraulic fluid reservoir (7).

Description

technical field [0001] The invention relates to a modular motor pump unit. In particular, the invention relates to a modular motor-pump unit for hydraulic applications. Background technique [0002] Such modular pump units are known from the prior art, for example from patent document EP2241753B1. These motor pump units usually have an outer housing with two open ends, whereby the two open ends can be closed by two attachable housing covers. The outer housing with the housing cover thus forms the hydraulic fluid reservoir. An electric motor and at least one pump element driven by the electric motor are arranged in the outer housing. The pump element may eg be a radial piston pump element or a gear pump element. It is also conceivable that more than one pump element is arranged in the outer housing. Electric motors typically have a stator that is secured in a stator seat within a housing. [0003] A connection section having at least one pressure connection and at least...
