Piston pump for use in home, has piston with drive that is implemented as electromagnet that is arranged such that it together works with permanent magnet and unit implemented as return valve, where pump has smaller diameter
摘要
<p>The pump has a cylinder (1) with a piston (2) that is arranged in a hollow space of the cylinder, where the pump has a smaller diameter. A drive of the piston is provided and a unit is implemented as a return valve (4) for admitting a fluid to be pumped in the hollow space. A part of the piston is implemented as a permanent magnet whose axis is parallel to axis of the piston. The drive is implemented as an electromagnet that is arranged such that it together works with the permanent magnet.</p>
