An analysis of four glitches observed in the pulsar B1822-09 during the period 1994 - 1999 is presented. The main distinguishing feature of these glitches is that the sudden increase in rotational frequency is accompanied by a decrease in the frequency derivative. The largest change of the frequency derivative was measured in the fourth glitch. This glitch occurred around MJD 51054 and was characterized by rather a small increase in rotational frequency of Δν/ν=7{x}10-9, but a large decrease in the frequency derivative by { ~ }2.4 %. The first two glitches were observed practically simultaneously at two frequencies of 0.1 GHz in Pushchino, Russia and 1.6/2.3 GHz at HartRAO, South Africa. An analysis of the high- and low frequency timing data showed that glitches did not affect the pulse arrival times at different frequencies within 2 ms. Glitch signature was identical in the wide frequency range from 0.1 to 2.3 GHz. In addition, a more exact value of the dispersion measure was measured to be 19.383(3) pc cm-3.
