摘要： The present invention concerns a hydraulic element comprising a sleeve-shaped casing and a piston reciprocable in a longitudinal direction in the sleeve-shaped casing. To provide a hydraulic element for use in displacement pumps for conveying small amounts of liquid, in which the danger of breakage or deflection of the hydraulic element is reduced, it is proposed according to the invention that the piston has a cavity extending in the longitudinal direction and having a cavity entry, wherein there is provided a pin which extends through the cavity entry into the cavity and which is connected to the sleeve-shaped casing at the sleeve-shaped casing or by way of an intermediate element so that in a reciprocating movement of the piston a relative movement occurs between the piston and the pin. The present invention further concerns a displacement pump having the hydraulic element according to the invention.

摘要： A diaphragm pump having a conveying chamber and a working chamber, wherein the conveying chamber comprises a pressure connection and a suction connection, and the working chamber can be or is filled with a hydraulic fluid and is operatively connected to a pressure generator in order to apply an oscillating pressure to the hydraulic fluid, further comprising a diaphragm which has at least one diaphragm layer and a diaphragm core and which separates the conveying chamber and the working chamber from one another, and which can be moved from a pressure stroke position into a suction stroke position and back again, the volume of the conveying chamber in the pressure stroke position of the diaphragm being smaller than in the suction stroke position. The diaphragm is or can be brought into operative connection with a diaphragm return device comprising a traction rod, which applies or can apply a force to the diaphragm in the direction of the suction stroke position and further comprising a storage chamber for accommodating the hydraulic fluid, the working chamber and the storage chamber being connected to one another via a channel closed by a closure element.

摘要： A pressure retention valve including a housing having an inlet passage and an outlet passage that can be connected together and a separating diaphragm subdividing the housing into two portions, wherein, in operation of the valve, a first portion conveys fluid and a second portion is fluid-free. The valve further includes a valve seat defining an end of the inlet passage, arranged in the fluid-conveying portion of the housing, and has a first sealing surface, a shut-off body which is arranged movably in the fluid-conveying portion of the housing and has a second sealing surface, and a spring element having a spring force, which is arranged in the fluid-free portion of the pressure retention valve. The spring element is so arranged that its spring force prestresses the second sealing surface in the direction towards the first sealing surface so that in a position of the shut-off body that closes the valve the sealing surfaces are in engagement with each other and the shut-off body separates the inlet passage from the outlet passage. The inlet passage is so arranged that a fluid flowing in through the inlet passage in operation of the valve is applied to the shut-off body in such a way that the fluid exerts on the shut-off body a force which acts in opposition to the spring force of the spring element. The shut-off body has a guide portion which extends into the inlet passage, and the inlet passage is portion-wise of such a design configuration that it forms a guide bush in which the guide portion of the shut-off body is guidedly received.
