Serbo-Croat term or phrase: hidraulični ublaživač
There's one here, I get what it is, but need to know exactly what it is called in English! No wild guesses please, leave those to me :)

water hammer absorber/arrestor
Explanation:
Milićević J, Rečnik mašinske tehnike:
watwr hammer - vodeni udarac, hidraulički udar


water hammer
n.
1. A banging noise heard in a water pipe following an abrupt alteration of the flow with resultant pressure surges.
2. A banging noise in steam pipes, caused by steam bubbles entering a cold pipe partially filled with water.
(http://www.thefreedictionary.com/water hammer)


Hydropneumatic device
...
Liquid Shocks, Surge Pressures, and Water Hammer Prevention.
Confusion
Confusion from large numbers of phrases: In the activity of preventing liquid shocks, surge pressures, and "water hammer" there is general confusion, because there are at least sixty, English, two and three word phrases, with the same general meaning. The following need to be used in both singular and pluralization for internet searches:
Shock:
shock absorber, shock alleviator, shock arrestor, shock attenuator, shock suppresor, shock preventer.
Surge:
surge absorber, surge alleviator, surge arrestor, surge attenuator, surge preventer.
Water Hammer:
water hammer absorber, water hammer alleviator, water hammer arrester, water hammer attenuator, water hammer suppresor, water hammer preventer. Confusion from word implications:
The wrong implications:
Most of these phrases imply that the shock, the surge, or the water hammer is addressed after it has been created. In fact most of those phrased apply to hydropneumatic devices that PREVENT a high level of shock, surge, or hammer, from occurring at all. The named devices are rarely designed to respond to a pressure incident in a liquid which must have an approximate typical velocity of 1,440 meters per second.

„Water hammer absorbers absorb the pressure spikes in liquids that are not compatible with stainless housings by compression of gas bags. Water hammer absorber, typical gas bag of elastomer type for liquids that need a plastic housing.“
(http://www.water-hammer.com/water-hammer-absorber.htm)


„Water Hammer Arresters
...
When the fluid flows in the pipe, if the valve close suddenly and stop the flow, the kinetic energy will be changed into elastic resilience and create a serial positive and negative pressure wave vibrating back and forth in the pipe until the energy lost by friction. Especially when the pump stop, the fluid still flows by inertia and gravity also cause the fluid to flow back, and these two forces will cause the positive and negative pressure waves. The friction caused by the two waves will make the pipe vibrating and create noise. Hence, the life of the pump and the piping accessories will be affected and, at the same time, cause the uncomfortable noise. under such situation, to set up one or more sets of water hammer arrester will improve the situation.
Our company make use of the airbag principle to design water hammer arresters which will reduce the vibration by pressing air when the in-pipe pressure transfer to air chamber.“
