Abstract

A manufacturing method of a railway braking device is described comprising a main body arranged to receive at least partially:at least two different pneumatic or electro-pneumatic elements; andchannels connecting the at least two pneumatic or electro-pneumatic elements;the manufacturing method comprising the step of:constructing said main body of the railway braking device through additive manufacturing of a monolithic block provided with at least two seats for said at least two pneumatic or electro-pneumatic elements and said channels; a railway braking device is further described constructed by means of a manufacturing method of a railway braking device.

First claim

The invention claimed is:

1. A manufacturing method of a railway braking device comprising a single main body within which:
at least two different pneumatic or electro-pneumatic elements are received, the at least two different pneumatic or electro-pneumatic elements comprising at least two elements having structural or functional differences; and
channels connecting said at least two pneumatic or electro-pneumatic elements are formed;

the manufacturing method comprising:
realizing, via additive manufacturing, said main body of the railway braking device so as to comprise a monolithic block having at least two seats for receiving said at least two different pneumatic or electro-pneumatic elements and said channels connecting the at least two different pneumatic or electro-pneumatic elements, wherein all of the channels interconnecting the at least two different pneumatic or electro-pneumatic elements are formed within the realized single main body.

2. The manufacturing method of claim 1 , further comprising:
after realizing, via additive manufacturing, the main body of the braking device, receiving components of said at least two pneumatic or electro-pneumatic elements into the main body; and
after receiving components of the at least two pneumatic or electro-pneumatic elements, coupling closing elements to the main body, the closing elements being arranged to retain the components of said at least two pneumatic or electro-pneumatic elements in position in the railway braking device.

3. The manufacturing method of claim 2 , further comprising:
constructing said closing elements by means of additive manufacturing.

4. The manufacturing method of claim 2 , wherein a material used for additive manufacturing said main body is of a metallic type, and/or the material used for additive manufacturing of said closing elements is of the metallic type.

5. The manufacturing method of claim 1 , wherein said pneumatic or electro-pneumatic elements have respective pneumatic ports arranged to interface said railway braking device with a support flange comprising corresponding pneumatic ports, and wherein the method comprises
realizing, via additive manufacturing, said main body of the railway braking device so that the corresponding pneumatic ports are arranged in the main body so as to emerge from a single face of the main body of the railway braking device.

6. A railway braking device comprising:
a single main body within which at least two different pneumatic or electro-pneumatic elements are received, the at least two different pneumatic or electro-pneumatic elements comprising at least two elements having structural or functional differences, wherein
channels connecting the at least two pneumatic or electro-pneumatic elements are formed within the main body, wherein
the single main body includes a support flange, the support flange surrounding a periphery of a face of the main body and comprising at least two seats sized and configured for receiving the at least two different pneumatic or electro-pneumatic elements, wherein
each of the at least two different pneumatic or electro-pneumatic elements are positioned within the face of the main body, and wherein
the main body is realized by a manufacturing method comprising realizing, via additive manufacturing, the main body so as to comprise a monolithic block having the at least two seats for receiving the at least two different pneumatic or electro-pneumatic elements and the channels connecting the at least two different pneumatic or electro-pneumatic elements, wherein all of the channels interconnecting the at least two different pneumatic or electro-pneumatic elements are formed within the realized single main body.

7. The device of claim 6 , wherein at least one of said pneumatic or electro-pneumatic elements is a pneumatic relay valve.

8. The device of claim 6 , wherein at least one of said pneumatic or electro-pneumatic elements is a pressure relief valve.

9. The device of claim 6 , wherein the main body comprises a functional volume therein.

10. The device of claim 6 , wherein said pneumatic or electro-pneumatic elements have respective pneumatic ports arranged to interface said railway braking device with the support flange comprising corresponding pneumatic ports, and wherein
the corresponding pneumatic ports are arranged in the main body so as to emerge from a single face of the main body of the railway braking device, the single face being the face of the main body, and the corresponding ports positioned within respective ones of the at least two seats for receiving the at least two different pneumatic or electro-pneumatic elements.
