FIELD: pneumatic machines of shocking action, B25D9/26 class, that is pneumatic hammers. SUBSTANCE: 1. block head of striker is pushed forward by value equal to 0.5 - 0.7 of cylinder diameter. 2. Slide valve has 1:1 ratio of its outer diameter to length and it is made of material with specific density in limits of 2.2 - 3.6 g/cm. 3. Hammer does not have rubber sealing rings and has ring-type slot, that continuously feeds air to inlet radial holes of starting joint in amount of 10 - 15 % of total consumption. Fulfillment of the conditions allows to provide operation of hydraulic hammer in any positions under decreased pressure of compressed air (beginning from 0.15 MPa) and environmental temperature up to 100 C. EFFECT: improved design. 3 cl, 1 dwg |
