Embodiment Construction

[0028] In the following, identical or functionally identical elements are identified with the same reference numerals.

[0029] figure 1 Shows a schematic exploded view of a lubricant pump 100 according to the invention with a housing 102 consisting of, in addition to a pump housing floor section 104, a pump housing covering section 106, a storage container 108 and a storage container cover 110 components. as otherwise from figure 1As is known, the piston pump device 1 is arranged in the pump housing base section 104 , which will be explained in more detail below. The storage container 108 is used to hold a fluid, in particular a lubricant, and is filled with the fluid / lubricant via a filling opening 112 formed on the upper side of the storage container cover 110 . The insertion opening 112 is here covered by a cover element 114 , wherein the cover element 114 is arranged on a hinge 116 on the front side of the storage container 108 .

Abstract

The invention relates to a piston pump device (1), in particular for lubricant pumps, with a double piston (8), which has a working piston (8a) and a delivery piston (8b), which are interconnected by a piston rod (20), Wherein the working piston (8a) is arranged sealingly in the first housing part (10; 12), and the delivery piston (8b) is arranged sealingly in the second housing part (10; 12), so that the working piston (8a) and the first The housing part (10; 12) defines the working chamber (16) for the working medium, the delivery piston (8b) and the second housing part (10; 12) defines the delivery chamber (34) for the fluid, where the double piston (8) and / or the first and / or second housing part (10; 12) are produced from plastic, and the invention also relates to a lubricant pump (100) having such a piston pump device (1).

Description

technical field [0001] The invention relates to a piston pump device, in particular for a lubricant pump having a double piston with a working piston and a delivery piston, the two pistons being connected to each other via a piston rod, wherein the working piston is in a first housing part The delivery piston is arranged sealingly in the second housing part, such that the working piston and the first housing part define a working chamber for the working medium, and the delivery piston and the second housing part define a delivery chamber for the fluid. Background technique [0002] In piston pump devices known from the prior art with a double piston comprising a delivery piston and a working piston, the medium to be delivered is generally sucked in from the storage tank by means of the delivery piston through the creation of a negative pressure, and is then sucked in by means of the pressure exerted on the working piston. The pressure compresses and transports in the directi...
