Description
Filed Jan. 12, 1928 (Patented Feb. 24, 1931 v HA S- RE IDEL, or w Es AiinN, GERMANY" LI IBRIeAN'IVCOMPRESS QBQ i nriicalion fiEdJafi y 92 r In the lmownhigli pressurelubricant com ,press ors actuatedby hand the filling of the 'supply.container,'particularly with consist ent grease, isveryunsatisfactory, The filling o spaces more or less filled with air. The'oper- 1 ation of filling: is also tedious and the hands has" hitherto always been effected I by means of a trowel or by means ofa separatejfilling device. 1 The .re'sultofthislis that the filling carinever be of the required uniform density The mass'ofzgr'ea se with which the device is" filled is always liableto contain hollow and clothesarefrequently soiled whilst do-v ing this. The hollow spaces filledwith' air and distributed throughout the lubricantinf the supply container lead constantly to disturbances in operation of the, lubricant co n-' pressor. Accordingto the present invention the lubricant'is drawn directly into the sup ply container through the operating cylinder 1 by means of the follower piston due, tdt'he suction action. produced by the latter. For this purpose the nozzle together with the noni return-valvearemade suitablydetachable so that the operating cylinder or its extension can be used as,a free suction passage. The,
i compressor nozzle 'is therefore preferably V constructed in such a manner, different from the known constructions, that it forms a unit with the non-return valvewhich hitherto formed an accessory of the operating cylinder.- Itis loosely fitted, screwed ordetachably secured in any othernianner to the front portion of the lubricant compressor which forms the extension of the operating cylinder, and is preferably protected against loss and damage by a protecting cap which is screwed over'it. p
By reason of this construction of the lubricant compressor the filling ofthe sup-ply c011- taiiier can be effectedzrapidly, conveniently and uniformly whilst avoiding the-useof any auxiliary device." The lubricant can be with- I drawn completely and without the forma- 4t tainer by means of the follower piston.

This tubula-r shaft Z of'the nozzle Z0, insteadof beingloosely fittedj in'to position may-also be screwed into the operating-cylinderor secured thereto, so as to' be readily detachable, in any other suitable manner.
