It "ordered the endeavor, the pump enel entente summarized by the cylinder blocks, the practical even represent complete piston pumps on the one hand as small as possible and on the other hand as cheap as possible Manufacture · Dii5 small dimensions are therefore from bcsonderor Bedcutn: n £ because the cylinder blocks and the eccentric of the blood pressure pump in all cases in a bathroom the Arbeitsoflüasigkei'S arranged and the dimensions of the associated storage container and the plu3iGkeitsfulltaengG oapfindlicli von dor G: cässer of the one described by the cylinder blocks Puapenöleiaento bostiaai / cind »Since the Cylinder block © and di'D cit ihaoa connected parts in the Pump noUr £ even occur and one particularly labor and kosteaiaöfeasivcn Antoil bei dor Eerstollurc aor esiizon Pump auoinachon and also pumps of this type with increasing Use of hydraulic drives in large Stückiaahlea aur application lcoiaraen, confirms that Beatrobon, the Horstelluns of the boachriebonen through the cylinder blocks Puapesaolcsa ^ nto you: r> chGood to rationalizeoa

The invention is therefore based on the general task of finding small dimensions and a minimum of 2 lines in a cost-saving manner. - ~ .ate to create cylinder blocks of the type mentioned, which are efficiently mass-produced körrrmn »· ·

In order to solve this problem, the invention is based on the "knowledge, which is probably new at Hochloistungspuiipen, that the puncture elements contained in the cylinder blocks can advantageously be designed as storage elements. like valve, be, ■ ; _t

According to the invention, the particularly essential step in the construction of such a disposable element that can be efficiently manufactured is that, in a cylinder block of the type mentioned, the suction valve ncbat intermediate piece and the pressure valve are fastened in the cylinder block by means of non-leakproof fasteners Art (see the above literature reference) one has so far the suction and pressure valve © by screwing or

A further essential step zo. A rational VcOTerfeleaent. consists in making the suction valve and pressure valve the same. So far, aan in Eesol has provided for rack valve and suction valve sizes as well as different types of construction. So it is known from the already mentioned German patent 925 539, a relatively large poppet valve and axo pressure valve as a Jausrcntil. \ u.oineres ball valve vox'auGijhcn.

In order to avoid positive jams between the valve basket and the valve plates, it is known that the valve basket is made from a single insbcsondoro with oinor zontra · "loa bonrung vercehe-non, Amstorn" (similar construction of the applicant). With a ßolclion design of the valve cage, it is sufficient to caulk the valve cage if some arms of the anastern are cantilevered radially on the outside in support lugs for the valve spring and other anas, preferably alternately with the cantilevered arms, in the Öalto legs. Among other things, this has the advantage that the. Plüßsiekoitsströnung to the side is only rainiiaal and still there is sufficient fastening of the valve cage. It has "proven when the footboards ^ ach l'ragbeins projecting on both sides, on both the 2ra £ projecting part Fußteiioa is nnnn the Yorstcauauag

In the spring case, the Zvd.cchenctu.ck ic provided for mounting the suction valve must also be used. Cylinder body can be mounted sealingly by stiffening. As a precaution, it is provided that the intermediate piece inside the cylinder block is on an inaenkonsole of the Aufiiahaebohunter a sm. Outer edge of the receiving hole in front of ^ e-

It is even possible to be careful not to caulk the suction valve to a self-contained susaxaneühendon Yentil., Indein. the valve seat of the building valve is also designed as a Z ^ / ischenstilclc and mounted in the cylinder body solely via such a sealing rust-proof valve seat.

According to the invention, it is therefore preferably provided that an intermediate ring is inserted between the radially protruding feet of the valve cage and the console, which intermediate ring has a larger radial width than the feet of the valve cage.
